Constructions

From this topic, we will learn the construction of angles with the help of protractor. It mentions the use of protractor and several steps to measure the angles. Moreover, exercise is given to construct the angles.

This topic covers concepts such as Construction of a Rectangle when Adjacent Sides are Given, Construction of a Rectangle when One Side and Diagonal is Given, Construction of a Square when One Side is Given, Construction of a Parallelogram, etc.

This topic covers concepts such as Construction of a Quadrilateral, Construction of a Quadrilateral when Four Sides and One Diagonal are Given, Construction of a Quadrilateral when Two Adjacent Sides and Three Angles are Given, etc.

The topic elaborates on the construction of triangles. The exterior angle of a triangle is equal in measure to the sum of interior opposite angles. The total measure of the three angles of a triangle is 180 degrees.
