Ray

ariadnab759 — 2015-09-08 16:45:47 UTC

two rays that meet at a point but only at that point.

Parallel Lines

ariadnab759 — 2015-09-08 16:46:12 UTC

Segments that are equal in length

Midpoint

ariadnab759 — 2015-09-08 16:47:58 UTC

The point in the middle of a figure .(My hat is a hexagon and it has triangles forming a point in the middle)

Angle

ariadnab759 — 2015-09-08 16:48:26 UTC

the space that is measured in degrees between two intersecting lines at a point where they cross

Acute angle

ariadnab759 — 2015-09-08 16:48:46 UTC

An angle that measures less than 90 degrees

Right angle

ariadnab759 — 2015-09-08 16:49:03 UTC

An angle that measures 90 degrees

Obtuse angle

ariadnab759 — 2015-09-08 16:49:11 UTC

An angle that measures more than 90 degrees. (My eyebrows are obtuse angles)

Straight angle

ariadnab759 — 2015-09-08 16:49:24 UTC

an angle that measures 180 degrees (the wooden part going straight down)

Congruent angles

ariadnab759 — 2015-09-08 16:49:31 UTC

angles that are the same in measurement (these lines form angles that are the same measurments)

Perpendicular lines

ariadnab759 — 2015-09-08 16:52:24 UTC

Two lines that form right angles when crossed.

Perpendicular bisector

ariadnab759 — 2015-09-08 16:52:52 UTC

A perpendicular bisector is a line segment that

Angle Bisector

ariadnab759 — 2015-09-14 16:24:29 UTC

A ray that divides an angle into two congruent angles.

Perimeter

ariadnab759 — 2015-09-14 16:24:53 UTC

total distance around the edge of a figure (the distance around the triangle)

Circumference

ariadnab759 — 2015-09-14 16:25:00 UTC

The distance around the outside of a circle.

Area

ariadnab759 — 2015-09-14 16:25:17 UTC

The number of square units in a figure (all the little squares within the square)

Vertical Angles

ariadnab759 — 2015-09-14 16:25:29 UTC

Vertical angles are the opposite angles made by intersecting lines.

Adjacent angles

ariadnab759 — 2015-09-14 16:26:03 UTC

They are angles that have a same vertex

Complementary Angles

ariadnab759 — 2015-09-14 16:26:17 UTC

Two angles that measure up to 90 degrees.

Supplemtary Angles

ariadnab759 — 2015-09-14 16:26:32 UTC

angles that equal up to 180 degrees (the line that goes horizontally is your angle and then the line in the middle divides it and makes two angles that add up to 180)

Theorem

ariadnab759 — 2015-09-14 16:26:52 UTC

A statement that has been proven to be correct.

Paragraph proof

ariadnab759 — 2015-09-14 16:42:06 UTC

Is when you write out the steps you took to solve a problem.

Transversal

ariadnab759 — 2015-09-14 16:42:22 UTC

Two lines crossed by another line

Alternate interior angles

ariadnab759 — 2015-09-14 16:42:41 UTC

They are on the inside of the lines and are on opposite sides. (Yellow marks the spot)

Same Side interior angles

ariadnab759 — 2015-09-14 16:44:00 UTC

The angles formed by a transversal and are the same because they are on the same side and on the inside of the lines. ( Red marks the spot

Corresponding angles

ariadnab759 — 2015-09-14 16:44:24 UTC

Corresponding angles are formed when a traversal passes through two other lines. Angles are formed and the ones that match are called corresponding angles. (the green dashes mark the corresponding angles)
