A midpoint is the center of gravity (center of mass or average location) for all of the points. On this line, the midpoint is located in the middle, while the two end points could be seen on the end. I also could of used a pencil for this

A Plane is represented by a flat surface that extends without end and has no thickness.

Every one of those rectangle shaped drawers could be considered a plane, as they are flat have no thickness from the front and extend with no end from the front.

A bisector is a line that divides a line or an angle into two equivalent parts. In this clock you could use any one of the wooden pieces that stick out to be a bisector, and create angles that are divided into two equivalent parts.

Coplanar: Points and/or lines that belong in the same plane.
Collinear: Points that belong on the same line

This image is coplanar because there is a line inside the plane (the rectangle shaped drawer) and this image is Collinear because on each of the handle, the ends symbolize points on a line inside a plane. you could also use your imagination and put little letters with your own points on the handle just like a line!

A circle is a two-dimensional figure, which is round in shape where all the points on the surface of the circle are equidistant from the center point is called “P”. In this case, the circle is the mirror, and it's round in shape and all the points are equidistant from each other.

A plane figure with three straight sides and three angles. In both of these cases, the pattern on the box and the points sticking out on the clock are both triangles. the clocks wooden triangles are isosceles and the patterns of triangles on the box are right triangles.

All rectangles are squares, but the only difference between a rectangle and a square is that a square has to have all even sides. this square pillow has all equal sides and four right angles. (the angles look a bit squishy but there's lines on the pillow that are straight).

A rectangle is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square. In this case, the monitor is a rectangle because it has 4 straight sides and four right angles. Its sides horizontally are also longer then they are vertically.

A vertical Angle is each of the pairs of opposite angles made by two intersecting lines. My fan isn't exactly a perfect example of what a vertical angle would look like, but the fan blades are still aligned and intersect if you look at it without the middle of the fan. it also has pairs of opposite angles.

A straight Angle is an angle that is perfectly 180 degrees. In this photo The straw represents the straight angle and its trying to form half a circle (my sharpie skills are rough) to represent 180 degrees.

# data[].attributes.body
A right Angle is an Angle that is exactly 90 degrees, half of 180. My camera was on a slight angle when I took this photo but the bottom edge of the tv is perfectly straight and the edge going vertically Is going perfectly straight upwards making this angle 90 degrees. I can tell its 90 degrees because the left two sides make up the bottom left of a square in my head.

An obtuse angle is an angle that is greater then 90 degrees, In this case the part that's sticking up from the top of the Sun-lounger (the head rest) is the arm that's extending beyond 90 degrees making it obtuse. (the parts that are holding the top of the chair up could also be considered acute). >

An Acute Angle is an angle which is measuring less than 90 degrees. In this case, the tongs are constantly at an angle that is less then 90 degrees (a right angle)

A line segment is a part of a line that consists of two endpoints and all the points in between them. In this case, the line segment is the two endpoints located in one of the lines of a square tile, but the end of that line still continues, and the line segment is only a segment of the full line that runs through the tile. where the horizontal lines meet on the vertical line (the full line) those are the points that make up the segment.

parallel lines are two lines in the same plane that are at equal distance from each other and never meet. In this case the plane is my fridge and the two lines that are at equal distance from each other and never meet are the two refrigerator door handles.

A line is represented by a straight path that extends in 2 opposite directions without end and has no thickness. this picture is of a line I found in my backyard. it continues in two opposite directions and doesn't have a definitive end.

A point indicates a location and has no size. My example here is the end of the pen, it indicates the tip or point.
