Question

I need help with this math question ASAP! Ill give u brainiest also :)

Answer 1

Answer:

SAS Postulate

Step-by-step explanation:

Here we mark the sides accordingly

We see

• AC = CF (Given)
• BC = CE (Given)
• < ACB = < ECF ( Each of 90°, as we see the angles are vertically opposite to each other,so they must be equal)

Since <ACB and <ECF are the included angles between each two sides as shown in figure,we can easily apply SAS postulate in which

• S- Side
• A-Angle
• S- Side

Option A is correct.

Remember the order is very important. Here as A is in the middle of SAS Postulate,it signifies we have to be careful of the included angle.
