Fundamentals of Geometry
(1) Identify the pairs of complementary and supplementary angles. [6 × 1] = 6
(i) 120°,60°
(ii) 50°, 100°
(iii) 70°, 70°
(iv) 130°, 50°
(v) 120°, 60°
(vi) 50°, 40°
(2) Are similar figures congruent? Give examples. [1 × 2] = 2
(3) If the measures of two angles of a triangle are 25° and 60°, then find the measure of its third angle. [2 × 1] = 2
(4) Define similar geometrical figures with examples. [1 × 2] = 2
(5) Draw a circle with radius QR cm = 7 and find its diameter. [1 × 2] = 2
(6) How many diameters of a circle can be drawn. Draw a circle and trace at least ‘5’ different diameters. [1 × 2] = 2
(7) Draw a semicircle of a radius of 6cm. [1 × 2] = 2
(8) What is meant by the adjacent angles? [1 × 2] = 2
(9) Differentiate between major and minor arcs. [1 × 2] = 2
(10) What is the difference between complementary angles and supplementary angles? [1 × 2] = 2
(11) If A and B are two supplementary angles where as m∠A = 400. Then find the measure of B. [1 × 4] = 4
(12) What is a circle? [1 × 1] = 1
(13) Define the vertically opposite angles. [1 × 1] = 1
