X Y ‾ ≅ J K ‾ \overline{XY}\cong\overline{JK} X Y ≅ J K

X Y ‾ ≅ K L ‾ \overline{XY}\cong\overline{KL} X Y ≅ K L

Select the choices that correctly identify congruent corresponding parts of the images. (There is more than one correct choice)

∠ D ≅ ∠ J \angle D\cong\angle J ∠ D ≅ ∠ J

∠ B ≅ ∠ G \angle B\cong\angle G ∠ B ≅ ∠ G

∠ A ≅ ∠ F \angle A\cong\angle F ∠ A ≅ ∠ F

∠ C ≅ ∠ F \angle C\cong\angle F ∠ C ≅ ∠ F

Find x and the measures of the unknown sides of the triangle.

x = 6 J K ‾ , K L ‾ , a n d J L ‾ = 24 x=6\ \ \overline{JK},\ \overline{KL},\ and\ \overline{JL}=24 x = 6 J K , K L , a n d J L = 2 4

x = 4 J K ‾ , K L ‾ , a n d J L ‾ = 20 x=4\ \ \overline{JK},\ \overline{KL},\ and\ \overline{JL}=20 x = 4 J K , K L , a n d J L = 2 0

x = 3 J K ‾ , K L ‾ , a n d J L ‾ = 20 x=3\ \ \overline{JK},\ \overline{KL},\ and\ \overline{JL}=20 x = 3 J K , K L , a n d J L = 2 0

x = 5 J K ‾ , K L ‾ , a n d J L ‾ = 25 x=5\ \ \overline{JK},\ \overline{KL},\ and\ \overline{JL}=\ 25 x = 5 J K , K L , a n d J L = 2 5

Find x and the measures of the unknown sides of the triangle.

x = 12 R S ‾ a n d R T ‾ = 31 x=12\ \overline{RS}\ and\ \overline{RT}=31 x = 1 2 R S a n d R T = 3 1

x = 11 R S ‾ a n d R T ‾ = 30 x=11\ \ \overline{RS}\ and\ \overline{RT}=30 x = 1 1 R S a n d R T = 3 0

x = 13 R S ‾ a n d R T ‾ = 32 x=13\ \overline{RS}\ and\ \overline{RT}=32 x = 1 3 R S a n d R T = 3 2

x = 12 R S ‾ a n d R T ‾ = 32 x=12\ \overline{RS}\ and\ \overline{RT}=32 x = 1 2 R S a n d R T = 3 2

The corresponding parts theorem states that

Corresponding parts of congruent triangles are congruent

All triangles are equal to each other

The hypotenuse of a triangle is parallel to its base

All corresponding angles in a triangle add up to 130

Are these triangles congruent?

Not enough information to know for sure

What does CPCTC stand for?
