Question

1. The acute angles of a right angled triangle are in the ratio 1:2. Find the measure of the angles of the triangle.

2. Construct a triangle PQR in which QR = 4.6 cm, RP = 5.5 cm, and PQ = 6.3 cm. Measure its angles.

please right it on a paper and send the pic.

Answer 1

Answer:

(1) 5.3 cm

Steps of construction:

1. Draw line segment AB = 5.3 cm.

2. With A as centre and radius more than half of AB, mark two arcs, one above and other below the line AB.

3. With B as centre and same radius, draw two arcs cutting the previous drawn arcs and name the point of intersection as X and Y.

4. Join XY and name the point where this line cuts AB as point P.

XY is the perpendicular bisector of AB.

(2) 6.7 cm

Steps of construction:

1. Draw line segment CD = 6.7 cm.

2. With C as centre and radius more than half of CD, mark two arcs, one above and other below the line CD.

3. With D as centre and same radius, draw two arcs cutting the previous drawn arcs and name the point of intersection as A and B.

4. Join AB and name the point where this line cuts CD as point Q.

AB is the perpendicular bisector of CD.

(3) 3.8 cm

Steps of construction:

1. Draw line segment XY = 3.8 cm.

2. With X as centre and radius more than half of XY, mark two arcs, one above and other below the line XY.

3. With Y as centre and same radius, draw two arcs cutting the previous drawn arcs and name the point of intersection as A and B.

4. Join AB and name the point where this line cuts XY as point R.

AB is the perpendicular bisector of XY.

Answer 2

Step-by-step explanation:

let the triangle be ABC

where ∠ABC = 90° (as it is a right angle triangle)

Part 1

let the two angles be 'x'

x + x + 90° = 180° (angle sum property)

2x + 90° = 180°

2x = 180° - 90°

2x = 90°

x = 90/2

x = 45°

∴ The measurement of the two acute angle of the right angled triangle is 45°
