2 angles that have the same exact measurements

# data[].attributes.body
2 opposing angles that measure the same so 2,4 and 1,3

# data[].attributes.body
any angle that is 180 degrees

# data[].attributes.body
Any angle that is exactly 90 degrees

# data[].attributes.body
any angle that is larger than 90 degrees

# data[].attributes.body
any angle that is shorter than 90 degrees

# data[].attributes.body
A segments that cuts and angle intow 2 smaller angles both sides are always the same value.

# data[].attributes.attachment_caption
The direct middle of 2 points in this case it is b 

# data[].attributes.body
Like it says above it is 2 line segments that measure the same value

# data[].attributes.body
A line that intersects two planes in the example above xy divide the 2 planes

# data[].attributes.body
2 lines that no matter what will never intersect

# data[].attributes.body
The midpoint. of 2 intersecting line for example A is the Postulate 1-2 in the photo above.

A line segment is a line with no end points so in the picture where the dots are that is all of the line 

# data[].attributes.body
A Line is a 180 degree angle with 2 points to show that they are never ending

# data[].attributes.body
All collinear points are on the same line so that is A,B,P,Q.

# data[].attributes.body
Is this picture all the points inside the plane is coplanar so that is A,B,C,D.

# data[].attributes.body
Plane is the 2d surface of a shape so the yellow part is the plane.

The letter a is a point  and if there were a line going thought it it would a point on a line.
