​

Answer 1

Question:-

Measure of one angle of a parallelogram is 80°. Find the other three angles.

Answer:-

• Measures of the remaining angles are 80°, 80°, 100° and 100°.

To find:-

• All angles of parallelogram

Solution:-

• Property of parallelogram: Opposite angles are equal

Let us consider one of the adjacent angle as x°

Other adjacent angle = 80°

• sum of adjacent angles = 180°

$\implies \: x° + 80° = 180° \\ \\ \implies \: x° = 180° – 80° \\ \\ \implies \:x = 100°$

∴ Measures of the remaining angles are 80°, 80°, 100° and 100°.
