Step-by-step explanation:
Answer:
Yes, there is (ASA)
Step-by-step explanation:
Here, we have a side common to the two triangles. That makes S
Also, we can see an angle on both triangles, that makes A
Lastly, there is a right angle on both triangle
That makes another A
So we have the ASA to prove the congruence of the two triangles
There are four cards labelled '2' and there are four cards labelled '6'. Therefore, number of cards 2's or 6's = 4 + 4 = 8
