Which pair of triangles can be proven congruent by sas?

A.

Step-by-step explanation:

I JUST TOOK THE TEST

Triangles are polygon made up of 3 line segments.

A triangle has 3 sides , 3 vertices and 3 angles.

SAS congruence criteria defined as Side-Angle-Side.

Therefore, If 2 sides of a triangle is equal to 2 sides of other triangle and angle made by equal side of a triangle is equal to the angle made by equal sides of other triangle. Then both triangles are said to be congruent by SAS rule.

For ex,

In ΔABC

AB = 6 cm , CB = 7 cm and ∠B = 80°

& In  ΔXYZ

XY = 7 cm , ZY = 6 cm and ∠Y = 80°

here AB = ZY , CB = XY and ∠B = ∠Y

So, we can say ΔABC ≅ ΔXYZ by SAS congruence Rule.

x=66

Step-by-step explanation:

2×x-2=x+64

2x-2=x+64

2x-x=64+2

x=66
