Can someone please help me with this geometry proof? It needs to get done ASAP and I'm really struggling.
1 answer:
One way to prove that the triangles are congruent is to show that the three pairs of sides have the same length.
For side , this is easy, since it is shared by the two triangles, so it is obviously equal.
On the other hand, we know that the given figure is a parallelogram, the opposite sides are equal in length. Particularly, it means that:
Thus, we have shown that each pair of sides have the same length, which means that:

Answer:
- given below
Step-by-step explanation:
1)
total area = rectangle area + 2 triangle area
= length * width = 2 ( * base * height )
= 7.5 * 6 + 2 ( * 3 * 4 )
= 57 ft²
2)
separate it into two rectangles:
length * width + length * width
6 * 2 + 9 * 4
48 cm²
3)
parallelogram area = base * height
= 20 * 25
= 500 in²
