Answer explanation

Not enough information given!

When using hypotenuse leg (HL) in a proof, you must first state ...

• CPCTC.

• there are right triangles.

• that vertical angles are congruent.

• the reflexive property.

The triangles are congruent. Which of the following statements must be true?

• ∠A ≅ ∠D

• ∠B ≅ ∠E

Which is the correct congruency statement?

• ∠ACB ≅ ∠ DFE

• ∠ BAC ≅ ∠ FDE

• ∠CAB ≅∠FED

• ∠ABC ≅ ∠ DEF

△BAC ≅ △QPR. If ∠B = 2x and ∠Q = 10, find the value of x.

• 2

• 12

• 5

• 8

Are these triangles congruent?

• Yes, by SAS

• No they are not congruent

• Yes, by SSS

• Not enough information to know for sure

What is the "statement" for step 3 of the proof?

• ∡EDA≅∡DCB

• ∡AED≅∡BEC

The Pythagorean Theorem only works on what type of triangle?

• Scalene

• Isosceles

• Obtuse

• Right

• All Triangles

means having the same shape and size

• congruent

• small

• large

• equal

The triangles below are similar. Find the missing side length.
