Question 1
In ΔABC, D and E are points on the sides AB and AC respectively, such that DE||BC. If AD = 4 cm, DB = 11 cm, AE = 7 cm and BC = 15.6 cm, then the sum of the lengths of DE and EC (in cm) is:
Question 2
The sides of a triangle are in the ratio 4 : 3 : 2. If the perimeter of the triangle is 63 cm, then what will be the length of the largest side?
Question 3
In the diagram, M is the midpoint of YZ, ∠XMZ = 32°, and ∠XYZ = 16°. The measure of ∠XZY is:
Question 4
The area of an equilateral triangle is half the area of a square. The ratio of the side of the said triangle and an edge of the square is:
Question 5
The area of ΔPQR is 8 cm2 and area of ΔABC is 18 cm2 and BC = 5 cm. If ΔPQR ~ ΔABC, then the length of QR is:
Question 6
The corners of an equilateral triangle ABC whose side is 15 cm are cut to form a regular hexagon PQRSTU. Then, what is the length of side of the hexagon?
Question 7
In a ∆ABC, 2∠ABC = 9∠ACB and 2∠BAC = 7∠ACB. If AB = 8 cm, AC = 17 cm, then the length of BC is
Question 8
In Δ PQR, S and T are mid-points of PQ and PR, respectively. If ∠QPR = 75° and ∠PRQ = 40°, then ∠TSQ is:
