Assume abc=pqr which of the following congruence statements are correct?Check all that apply
aev [14]
Hello!

You go by the notation of the triangles

AB = PQ

Since both of them are the first two letters to label the triangles this is true
------------------------------------------------------------------------------------------------------
<R = <C

Since they are both the last letter in the triangles this is also true
------------------------------------------------------------------------------------------------------
<C = <P

They are not in the same place so this is not true
------------------------------------------------------------------------------------------------------
<A = <Q

Since they are in different spots this is not true
------------------------------------------------------------------------------------------------------
BC = PQ

Since they are in different spots this is also not true
------------------------------------------------------------------------------------------------------
AC = QR

Since they are in different spots this is not true also
------------------------------------------------------------------------------------------------------
The answers are A and B

Hope this helps!

Determine whether the triangles are congruent. Explain your reasoning .
Vanyuwa [196]

Answer:

The triangles are congruent by congruency theorem SAS.

Step-by-step explanation:

Side-Angle-Side, as it suggests, is when a triangle is congruent by the order of congruent side, congruent angle, and another congruent side. If named certain ways, they can be congruent. Since the question does not provide a specific way of naming the triangles, we can assume that any way is allowed. 2.5 and 2.5 are congruent, followed by angles D and G which have the congruent angle markers. The congruent angles are followed by 1.7 and 1.7, making the triangles congruent by Side-Angle-Side.
