Left side and right side each 3 cm.
Top and bottom side each 4 cm.

Angle alpha is the upper right as well as the lower left angle of the parallelogram. Show the altitude from the vertex at lower right, to the upper base, meeting perpendicularly. This forms a right triangle on the right side of the figure.

Draw the other altitude, from the same lower right vertex to the left side meeting perpendicularly. This forms another right triangle at the bottom of the figure, with one sidc 4 cm and the angle at the lower left of this figure, part of the triangle, is also alpha. YOU WANT TO KNOW or FIND THE OTHER LEG, which is the same as that altitude. The hypotenuse is 4 cm. Think carefully about this triangle. Call this altitude and leg, a.
