Give two measures of (i) acute angle (ii) obtuse angle.

3.write down the measures: (a) some acute angles (b) some obtuse angles.4. Measure the angles given below using the Protractor and write down the measure

If the roots of the equation c^(2)x^(2)- c(a+b)x + ab =0 are sin A, sin B where A, B and C are the angles and a, b, c are the opposite sides of a triangle, then the triangle is : (i) right angled (ii) acute angled (iii) obtuse angled (iv) sin A + cos A = (a+b)/(c )

An angle of measure 140^(@) is an acute angle (b) an obtuse angle a straight angle (d) a complete angle

Write down the measures of (a) some acute angles.(b) (b) some obtuse angles (give at least two examples of each)

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

Can a triangle have: Two right angles? (ii) Two obtuse angles? Two acute angles (iv) All angles more than 60^0 ? All angles less than 60^0 ? (vi) All angles equal to 60^0
