WebApr 6, 2024 · The values of the opposite angles of a parallelogram are given as follows: ∠1 = 80°, ∠3 = (2x – 10)°. Find the value of x. Solution: Since opposite angles of a parallelogram are congruent, we have: ∠2 = ∠1 = 80° Also, since consecutive angles of a parallelogram are supplementary, we have: ∠3 + ∠2 = 180° WebThe shape has one set of parallel sides and does not have any right angles.

WebThe quadrilateral is a parallelogram. Opposite angles are equal. \[g = 50^\circ\] Angles in a quadrilateral add up to 360° and opposite angles are equal. \[f = \frac{360 - 50 - 50}{2} = … WebThe opposite angles are equal in a parallelogram. Proof: Using Theorem 3, we can conclude that the pairs of opposite angles are equal. (i.e) ∠A = ∠C and ∠B = ∠D Thus, each pair of … WebAnd if opposite sides have the same length, then you have a parallelogram. And so we've actually proven it in both directions. And so we can actually make what you call an "if and … hold note circuit
