WebThe height = 32 cm. ∴ the area of the parallelogram = base × height. ∴ 256 = base × 32. The base = 256 32 = 8 cm. Example: Find the area of a parallelogram, two adjacent sides of which are 17 cm and 20 cm and their included angle is 60 ∘. Solution: Here, one side b = 17 cm, the other side c = 20 cm, and θ = 60 ∘. ∴ the area = b c ...

WebFeb 2, 2024 · The answer is 75. We use the formula that says the area is equal to ½ times the product of the lengths of the diagonals times the sine of the angle between them. As our diagonals are perpendicular, the angle between them is 90° and sin 90° = 1. Hence, the calculation we need to perform is ½ × 10 × 15 = 75. Hanna Pamuła, PhD. WebA parallelogram is a quadrilateral with opposite sides parallel. A parallelogram whose angles are all right angles is called a rectangle. And, a parallelogram whose angles are all right … WebASA (Angle-Side-Angle): If two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent. The ASA Postulate was contributed by Thales of Miletus (Greek). In most systems of axioms, the three criteria—SAS, SSS and ASA—are established as theorems. fish lord blox fruits
