How can you show that a parallelogram and a rectangle with the same bases and heights have equal areas?
We can see why this is true by decomposing and rearranging the parallelograms into rectangles. Notice that the side lengths of each rectangle are the base and height of the parallelogram. Even though the two rectangles have different side lengths, the products of the side lengths are equal, so they have the same area!
What is the relation between area of triangle and parallelogram standing on same base between the same parallels?
If a triangle and a parallelogram are on the same base and between the same parallels, then the area of triangle is equal to half the area of the parallelogram. In the adjoining figure, parallelogram ABCD and ∆ABD are on the same base AB and between the same parallels AF and DC.
How do you prove ABCD is a rectangle?
– The diagonals are congruent. Let’s see why we can claim that the diagonals are congruent. Here is a sample proof: Given: Quadrilateral ABCD is a rectangle….Prove it is a Rectangle.

| ΔBCD ≅ ΔADC | Side, Angle, Side |
| AC ≅ BD | CPCTC |
Can a triangle and a parallelogram have the same area?
Heron’s Formula A triangle and a parallelogram have the same base and the same area.
What is the relationship between a parallelogram and a triangle?
We see that each triangle takes up precisely one half of the parallelogram. From this, we see that the area of a triangle is one half the area of a parallelogram, or the area of a parallelogram is two times the area of a triangle.
What do parallelograms on the same base and between the same parallels?
Parallelograms on the same base and between the same parallels are equal in area. Area of a parallelogram is the product of its any side and the corresponding altitude. Parallelogram on the same base and having equal areas lie between the same parallels. Two congruent figures having same area.
What is the area of the parallelogram ABCD?
Answer: In parallelogram ABCD, CD = AB = 16 cm [Opposite sides of a parallelogram are equal] We know that Area of a parallelogram = Base × Corresponding altitude Area of parallelogram ABCD = CD × AE = AD × CF 16 cm × 8 cm = AD × 10 cm 5
Is ABCD a parellelogram?
Given: ABCD is a parellelogram. Prove: AB=CD and BC=DA – Brainly.com Given: ABCD is a parellelogram. We have given a parallelogram ABCD. Opposite pair of sides are parallel to each other. i.e AD is parallel to BC and AB is parallel to CD.
How do you find the area of a parallelogram and triangle?
If a parallelogram and a triangle are on the same base and between the same parallels, then area of the triangle, is half the area of the parallelogram. Two congruent figures having same area. Triangles on the same base and between the same parallels are equal in area.
