A triangle whose one angle is more than 90^0 is called (a) a scalene triangle (b) a right triangle (c) an acute triangle (d) an obtuse triangle

What is the measure of (i) a right angle? (ii) a straight angle?

A reflex angle measures

An angle is 30^(@) larger than a straight angle. Find the angle

Match the following :Measures of Triangle Type of Triangle(i) 3 sides of equal length (a) Scalene(ii) 2 sides of equal length (b) Isosceles right angled(iii) All sides are of different length (c) Obtuse angled(iv) 3 acute angles (d) Right angled(v) 1 right angle (e) Equilateral(vi) 1 obtuse angle (f) Acute angled(vii) 1 right angle with two sides of equal length (g) Isosceles

Say True or False : (a) The measure of an acute angle <90^@ . (b) The measure of an obtuse angle <90^@ (c) The measure of a reflex angle <180 6@ (d) The measure of one complete revolution =360^@ . (e) If m?
