Solution:

QUESTION: 3

In the Pythagoras property, the triangle must be ___________ .

Solution:

QUESTION: 4

Find the value of x in this figure.

Solution:

QUESTION: 5

Find the value of x in given figure.

Solution:

Exterior angle is equal to sum of interior opposite angles so,

120 = 60+x

x = 60^{°}

QUESTION: 6

In ΔPQR, PD is

Solution:

Median is a line joining the vertex and middle of the opposite side, and hence dividing the triangle in two equal parts. So PD is the median.

QUESTION: 7

The value of x in the adjoining figure is

Solution:

QUESTION: 8

What is the value of x in the below figure.

Solution:

QUESTION: 9

Find the value of unknown x in the adjoining figure.

Solution:

QUESTION: 10

What is the measure of angle x ?

Solution:

QUESTION: 11

ΔABC is right-angled at C. If AC = 5 cm and BC = 12 cm find the length of AB.

Solution:

AB^{2}=AC^{2}+BC^{2}=5^{2}+12^{2}=25+144 = 169

AB=13 cm

QUESTION: 12

ΔPQR is a triangle right-angled at P. If PQ = 3 cm and PR = 4 cm, find QR.

Solution:

Using pythagoras theorem,

QR^{2 }= PR^{2 }+ PQ^{2}

4^{2}+3^{2}

=16+9=25

QR = 5cm

QUESTION: 13

Which is the longest side in the triangle PQR right angled at P?

Solution:

QUESTION: 14

Which is the longest side in the triangle ABC right angled at B?

Solution:

QUESTION: 15

Which is the longest side of a right triangle?

Solution:

QUESTION: 16

What is the measure of angles x?

Solution:

Since the two sides are equal, the angles opposite to them are also equal. So x+45° + 45° = 180°, x = 90°

QUESTION: 17

The value of x in the adjoining figure is

Solution:

QUESTION: 18

A triangle in which all three sides are of equal lengths is called _________.

Solution:

QUESTION: 19

Find angle x in below figure

Solution:

QUESTION: 20

Find angle x in below figure.

Solution:

Since the two sides are equal, the angles opposite to them are also equal to the adjacent angle of 120° which is equal to 180° - 120° =60° is equal to x. So x = 60°
