In the figure, ABCD is a parallelogram. Given that OD = 5 cm and AC is 2 cm less than BD. Find OA.
Given a parallelogram ABCD. Complete each statement along with the definition or property used.
Draw a rough figure of a quadrilateral that is not a parallelogram but has exactly two opposite angles of equal measure.
The measures of two adjacement angles of a parallelogram are in the ration 3 : 2. Find the measure of each of the angles of the parallelogram.
Two adjacent angles of a parallelogram have equal measure. Find the measure of each of the angles of the parallelogram.
The interior angle of a regular is 108°. Find the number of sides of the polygon.
Let there are ‘n’ sides of the regular polygon.
Thus, the measure of the angle of the quad, are 36°, 12°, 108° and 144°.
Thus, the required number of sides of the regular polygon is 5.
