## Karnataka State Syllabus Class 7 Maths Chapter 10 Practical Geometry Ex 10.5

Question 1.

Construct the right angled ∆ PQR? where m∠Q = 90°, QR = 8 cm and PR = 10 cm.

Solution:

Solution:

Steps of Construction

- Draw a line segment of length 8 cm and named as QR. At Q draw QM ⊥ QR.
- With R as centre, draw an arc of radius 10 cm and cut the ⊥
^{le}line at P. - Join PR. Now we get the required PQR ∆

Question 2.

Construct a right-angled triangle whose hypotenuse is 6 cm long and one of the legs is 4

cm long.

Solution:

Steps of Construction

- Draw a line segment of length 4 cm and named it AB. At A draw a ⊥ line AM.
- With B as centre, draw an arc of 6 cms cut the x line at ‘C ’. Now we obtained the required triangle ABC.

Question 3.

Construct an isosceles right-angled triangle ABC, where m∠ACB = 90° and AC = 6 cm.

Solution:

Steps of Construction

- Draw a line segment of 6 cm, ie., AC. At C draw CM ⊥ CA.
- With ‘C’ as the centre draw an arc of radius 6 cm to intersect CM at ‘B’
- Join AB. Now we get the required ∆ACB.
