Answer:
likley
Step-by-step explanation: edge 2021 on the quiz for me its question 6
1. Consider the parallelogram ABCD drawn in the 1. figure attached.
2. The diagonals of a parallelogram bisect each other, so AM=MC and BM=MD
3. In triangle ABC, BM is an altitude (BM perpendicular to AC), but also a median (AM=MC). An altitude is also a median only when the triangle is isosceles, so AB=BC
similarly, in triangle BCD, CM is both an altitude and a median.Thus, BCD is an isosceles triangle so BC=CD.
4. AB= DC (opposite sides of a parallelogram are equal), similarly BC=DA
5. So ABCD is a quadrilateral, with all 4 sides equal in length. Thus ABCD is a rhombus.
A) 40
b) 3
c) 5
Hope this helps
