The diagonal of a parallelogram always bisect each other. All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary). Hence, it is proved that the opposite angles of a parallelogram are equal. Two consecutive angles in a parallelogram are in the ratio 5:4. Therefore, it will become a rectangle. Constructing Perpendicular from Point to Line. Therefore we have proved that opposite angles of parallelogram are equal. Check-out the interactive simulation to know more about the lesson and try your hand at solving a few interesting practice questions on consecutive angles at the end of the page. For example m∠ABD + m∠BDC =180°. Explanation: In a parallelogram, consecutive angles are supplementary (i.e. #4x + 11x = 180# #=> 15x = 180# #=> x = 12# #=> A_1 = 4x = 48# #=> A_2 = 11x = 132# Since we are dealing with a parallelogram, its opposite interior angles are equal. If any of the angles of a parallelogram is a right angle, then its other angles will also be a right angle. Done in a way that not only it is relatable and easy to grasp, but also will stay with them forever. Given, $ \angle W = (\text a - 10)^\circ $, Since $ \angle W $and $ \angle X $ are consecutive angles, we can write-, \[ \angle W + \angle X = 180 \] On substituting the given values, we get-\[ \begin{align*} (\text a - 10) + \angle X &= 180 \\ 70 - 10 + \angle X &= 180 \\ \angle X &= 180 - 60 \\ \angle X &= 120 \end{align*} \], Similarly, $ \angle X $and $ \angle Y $ are consecutive angles, hence we can write-, \[ \angle X + \angle Y = 180 \] On substituting the values, we get- \[ \begin{align*} 120+ \angle Y &= 180 \\ \angle Y &= 180 - 120 \\ \angle Y &= 60 \end{align*} \]. 2x+3x+2x+3x=360 (sum of angles in a parallelogram is 360) 10x=360 x=36 Angles are 2x=36×2=72 3x=36×3=108.
