Geometry Congruent Figures

Remember order matters. Which of the following is true?

• ∆JLK ≅ ∆XWJ

• ∆LJK ≅ ∆JWX

• ∆JKL ≅ ∆JXW

• ∆LKJ ≅ ∆JXW

Which statement indicates that the triangles in each pair are congruent.

• ∆LMK ≅ ∆LMT

• ∆LMK ≅ ∆TMK

• ∆LTKM ≅ ∆LMT

• ∆TMK ≅ ∆TLK

Let's play a game of match-the-triangles! Can you tell which of the following pairs of triangles are congruent? Remember, the order of vertices matters!

• ∆FGH and ∆VHW

• ∆HFG and ∆HWV

• ∆HGF and ∆VHW

• ∆FGH and ∆VWH

Matching sides are called

• Corresponding Sides

• Corresponding Angles

• The Same

• Congruent Sides

Matching angles are called

• Corresponding Sides

• Corresponding Angles

• The Same

• Congruent Angles

All corresponding angles in congruent figures are congruent.  

• True

• False

How can you tell which Angles are congruent from ∆DEF ≅ ∆ZXY?

• I can not tell without a diagram.

• I can not tell without measurements given.

• I looked at the letters in corresponding positions.

• The letters closer to the beginning of the alphabet match and the letters closer to the end of the alphabet match.

x = 

• 9

• 11

• 17

If ∆PIG ≅ ∆COW, WO≅?

• GI

• PI

• PG

The figures are congruent. Name one pair of corresponding angles.

• Q and W

• R and Z

• S and Z

• T and P
