There isn't enough info to prove the triangles to be congruent or not. So we can't say for sure either way.
We have angle CAD = angle ACB given by the arc markings, and we know that AC = AC due to the reflexive theorem. However we are missing one third piece of information.
That third piece of info could be....
- AD = BC which allows us to use SAS
- angle ACD = angle CAB which allows us to use ASA
- angle ABC = angle CDA which allows us to use AAS (slight variation of ASA)
Since we don't know any of those three facts, we simply don't have enough information.
side note: If AB = CD, then this leads to SSA which is not a valid congruence theorem. If we had two congruent sides, the angle must be between the two sides, which is what AD = BC allows.

<u><em>The question is </em></u>
Find the measure of the legs
we know that
In a 45 degrees -45 degrees -90 degrees triangle, the measure of the legs are equal
Let
a ----> the measure of one leg
Applying the Pythagorean Theorem
solve for a
Divide by 2 both sides
Simplify

Step-by-step explanation:
Answer: The solids have the same types of vertical cross sections through the base are a rectangular prism and a cylinder (first option)
Solution:
a. The vertical cross section through the base of a rectangular prism is a rectangle.
b. The vertical cross section through the base of a cylinder is a rectangle.
c. The vertical cross section through the base of a cone is a triangle.
d. The vertical cross section through the base of a pyramid is a triangle.
Then:
First option is true.
Second option is false.
Third option is false.
Fourth option is false.
