Question

3. The angles of a triangle are in the ratio 1:3:5. Find the measure of each of the ang
EXERCISE 16A
Adding the corresponding sides of the above equations, we get:
1. Take three noncollinear points A, B and C on a page of your notebook. Join AB, BC and CA
2. The measures of two angles of a triangle are 72º and 58º. Find the measure of the third ang
2A + 2C + ZE=180°
In A BDF, we have:
ZB+ ZD+ ZF = 180°.
2A + 2B + 2C + 2D + ZE+ZF = 360°.
What figure do you get?
Name: (1) the side opposite to 2C
(11) the angle opposite to the side BC
(111) the vertex opposite to the side CA
(iv) the side opposite to the vertex B
4. One of the acute angles of a right triangle is 50°. Find the other acute angle.
5. One of the angles of a triangle is 110° and the other two angles are equal. What
measure of each of these equal angles?
6. If one angle of a triangle is equal to the sum of other two, show that the triangle is
triangle.
Hint. ZA = ZB+ 2C = ZA+ ZA = ZA+ZB+ ZC = 180°.
7. In a A ABC, if 3 LA = 42B = 62C, calculate the angles.
