there are straight edges on books measuring 180º

# data[].attributes.body
the two pieces of wood put together form two angles which are supplementary to each other

# data[].attributes.body
arrowes can be concidered lines because they extend in both directions

# data[].attributes.body
each angle made on this flag has a similar angle made above or below it

# data[].attributes.body
two distinct planes intersect to form a line and the planes shown are the walls in the house

# data[].attributes.body
The cake represents a circle

The top face of this cake is a triangle which has three sides

# data[].attributes.body
the signs are placed crossing eachother which forms verticle angles

# data[].attributes.body
These are paralle lines because they never cross

These pens are the same length so that means they are congruent

# data[].attributes.body
This desk is flat surface so it is a plane.

A line segment has to points one on either side of the line. A drum stick could be. concidered a segment

# data[].attributes.body
any two given points intersect at one point. There are two lines here that intersect eachother at a single point

# data[].attributes.body
The two acute pizza slices make up one big slice which is 90º so the two smaller angles are complimentary to eachother

# data[].attributes.body
There are thousands of examples of rectangles in real life they just have to be four side and have two sets of congruent lines.

This pizza reresents an acute angle because it measures less then 90º
