Geometric Reasoning

We know these lines are parallel because...

• The double arrows

• They look like it

• The letters

• They are black

Angles in a triangle add to...

• 180 $\degree$

• 360 $\degree$

• 90 $\degree$

• 204.6 $\degree$

What term refers to two lines that intersect at 90 degrees?

• Coincident

• Perpendicular

• Parallel

• Colinear

What is the difference between a shape and a solid?

• A shape is 2D and a solid is 3D

• A shape has straight lines and a solid has curved lines

• A shape is 3D and a solid is 2D

• Shape and solid are the same thing

Angles that sum together to equal 180 degrees

• supplementary angles

• complementary angles

• congruent angles

These alternate angles are...

• 30 $\degree$

• Equal

• 180 $\degree$

• 80 $\degree$

The equal angles here are...

• Vertically opposite

• Congruent
