Find the area of the rhombus. 16 in. 9in. The area of the rhombus is in2​

State if the two triangles are congruent. if they are, state how you know?

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.

Can someone me with these two circle theorem questions asap?
