Triangle

A triangle is a polygon with three angles and three sides. The sum of the three angles is always 180 degrees.

What is a triangle?

In each triangle one side is always less than the sum of the other two and greater than their difference. the, in full and the sum of the three sides, in the triangle there are no diagonals.

The triangles are classified into three categories based on the length of the sides and are escaleno triangles and social triangles and equilateral triangle

Classification

Equilateral triangle: three equal sides three equal angles, always 60º

Equilateral triangle

E social triangle: has two equal sides and two equal angles.

Esocial triangle

Scalene triangle: has no side and no equal angle

Scalene triangle

Title An acute triangle is a triangle which has all the angles less than 90°

Acute triangles

A right triangle has an angle of 90°

Right triangle

They are congruent angles, two angles They are congruent angles, two angles that when superimposed coincide point by point. Therefore two angles are said to be congruent if, by means of a rigid movement, it is possible to superimpose them so that they have the same vertex and their sides coincide.

When are two triangles called congruent?

An obtuse triangle has an angle greater than 90°

Obtuse triangle

The Pythagorean theorem tells us that in all right triangles the area of ​​the square built on the hypotenuse is equal to and the sum of the areas of the squares constituted on the catheti. the hypotenuse is the longest side of the rectangle and is located in front of the right corner

Polygons

Cristina Gorceag, Edoardo Porta, Sara Salmoiraghi, Andrea Scozia

A polygon is a plane shape with straight sides.Polygons are 2 dimensional shapes. They are made of straight lines and the shape is closed.The word POLYGON comes from Greek. POLY means "many" and GON means "angle".

What is a polygon?

Is it a polygon?

Yes, these figures are polygons

No, these figures are not polygons

What is the difference between a regular and an irregular polygon?

A regular polygon has all angles equal and all sides equal, otherwise it is irregular.

This polygon is regular

This polygon is irregular

Is it a regular polygon?

What is a concave polygon and what is a convex polygon?

A convex polygon has no angles pointing inwards.More precisely, no internal angle, can be more than 180°In any internal angle is greater than 180° the polygon is concave.

Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis.

This polygon is concave

This polygon is convex

What is the sum of interior angles of a polygon?

An interior angle is an angle inside a shape.The general rule for the sum of internal angles is:Sum of interior angles= (number of sides-2) . 180°Each angle (of a regular polygon) = (number of sides -2) . 180° / number of sides.

What is the sum of the exterior angles of a polygon?

The exterior angle is the angle between any side of a shape, and a line extended from the next side.When we add up the interior angle and exterior angle we get a straight line 180°. They are "supplementary angles"The exterior angles of a polygon add up to 360°.The general rule for the sum of exerior angles is:Sum of exterior angles (for each regular polygon) = 360°Each angle= 360/ number of sides

What is symmetry?

In mathematics, a symmetry is an operation that moves or transforms an object while leaving its appearance unchanged. The object can be, for example, a geometric figure or an equation.

When does a figure have rotational symmetry?

A figure has Rotational Symmetry when it still looks the same after some rotation (of less than one full turn).

When does a figure have a line symmetry?

Reflection Symmetry (sometimes called Line Symmetry or Mirror Symmetry) is easy to see, because one half is the reflection of the other half.Many figures can be divided into two perfectly equal parts. When this happens, it is said that the two parts of the figure are symmetrical. The line that separates them is called the Line of Symmetry (also called the "Mirror Line") Not all shapes have lines of symmetry, or they may have several lines of symmetry.

What kind of symmetry do the main regular polygons have?

The main regular polygons have a line symmetry.Regular polygons have a number oflines of symmetry equal to the number of sides.

An equilateral triangle (3 sides) has 3 lines of symmetry.

A square (4 sides) has 4 lines of symmetry.

A regular pentagon (5 sides) has 5 lines of symmetry.

A regular hexagon (6 sides) has 6 lines of symmetry.

A regular heptagon (7 sides) has 7 lines of symmetry.

A regular octagon (8 sides) has 8 lines of symmetry.
