RD=5 cm, AD=7 cm, R=125°, E = 105°,
A=100
Answers
Answer:
EXERCISE : 4.5
Draw the following:
1. The square READ with RE = 5.1 cm.
Sol. Draw a rough sketch of the required square and write down its dimensions. Steps of construction: 1. Draw RE = 5.1 cm
2. Draw RX ⊥ RE. 3. With R as centre and radius 5.1 cm, draw an arc to cut RX at D. 4. With D as centre and radius 5.1 cm, draw an arc. 5. With E as centre and radius 5.1 cm, draw another arc cutting the previous arc at A. 6. Join DA and EA. Then READ is the required square.
2. A rhombus whose diagonals are 5.2 cm and 6.4 cm long.
Sol. Let diagonal AC = 5.2 cm and diagonal BD = 6.4 cm
Draw AC = 5.2 cm. Draw XY, the perpendicular bisector of AC which cuts AC at O. With O a centre, draw arcs of radii
which cut OX at D and OY at B. Join AB, BC, CD and DA. Then, ABCD is the required rhomb
