(PA) Unit 7 Lesson 3 - Angle Pair Definitions

Multiple Choice

True or False: The triangle with side lengths 9, 12, 15 is a right triangle.

Verify your answer using DESMOS. This is not a race, but start now!

• True

• False

Multiple Choice

Which set of sides would make a right triangle?

• 4, 5, 6

• 8, 10, 12

• 5,12,13
• 5, 10, 12

Multiple Choice

Which Pythagorean Triple (three side lengths) does the picture illustrate?

• 4, 5, 6

• 2, 3, 4

• 3, 4, 5

• 1, 2, 3

Multiple Choice

Which type of side length is missing in this diagram?

• Leg

• Hypotenuse

• A right Angle

Multiple Choice

Which sequence of calculations in DESMOS would find this missing leg length?

Multiple Choice

Which angle is "Vertical" to $$\angle ABE$$

• $$\angle CBD$$

• $$\angle DCB$$

• $$\angle CBE$$

Multiple Choice

Which angle is Complementary to $$\angle ABE$$ ?

• $$\angle GEB$$

• $$\angle CBG$$

• $$\angle EBG$$

Poll

Note: Complementary angles do not need to be adjacent. They don't actually need to be connected at all ... their measure in degrees just have to add up to 90.

Which angle, other than $$\angle EBG$$ , is also complementary to $$\angle ABE$$ ?

• $$\angle CBD$$

• $$\angle DBF$$

• $$\angle ABF$$

Multiple Choice

There are actually two angles supplementary to $$\angle CBE.$$ Which angle is NOT supplementary to angle CBE, highlighted in green?

• $$\angle ABE$$

• $$\angle ABD$$

• $$\angle CBD$$
