The cyclical quadrilateral Rhombus has all its sides equal. The angles (opposite) are equal. Adjacent angles are supplementary (sum to 180 deg).
Side = perimeter / 4 = 5 cm
The two different Angles are : 70 deg and 180 - 70 = 110 deg.
1. Draw a line segment AB horizontally of length 5 cm.
2. Draw a line segment (from A) at an angle of 70 deg to AB using a protractor. Measure 5 cm from A on this line and mark it as C. Or, using a compass draw an arc with radius 5 cm with center as A to cut this inclined line at point C.
3. Draw a line segment from B at angle of 110 deg to AB, on the same side as AC.
4. Now using a compass draw an arc with radius 5 cm to cut the inclined line at D.
Join ABCD, to get the Rhombus.
