Name of the triangle |
Measure of first angle |
Measure of Second angle |
Measure of third angle |
Sum of the measure of three angles |
|---|---|---|---|---|
|
ABC |
∠A = 60° |
∠B = 60° |
∠C = 60° |
∠A + ∠B + ∠C = 180° |
|
DEF |
∠D = 60° |
∠E = 40° |
∠F = 80° |
∠D + ∠E + ∠F = 180° |
|
PQR |
∠P = 44° |
∠Q = 90° |
∠R = 46° |
∠P + ∠Q + ∠R = 180° |

XYZ |
∠X = 30° |
∠Y = 110° |
∠Z = 40° |
∠X + ∠Y + ∠Z = 180° |

1. In the following statements put (√) in the correct one and (x) in the incorrect one.
(i) Four sides of rectangle are equal.
Ans: ×
(ii) For a parallelogram, both the pair of the opposite sides are parallel.
Ans: √
(iii) Every angle of a rhombus is 90°
Ans: ×
(iv) Each rectangle is a parallelogram.
Ans: √
(v) Each parallelogram is a rhombus.
Ans: ×
(vi) Each square is a rectangle.
Ans: √
(vii) If the four sides of a rectangle are equal, then it will be a square.
Ans: √
(viii) All the four sides of a square are of equal length.
Ans: √
(ix) If the other pair of sides of a trapezium is also parallel, then it will be a parallelogram.
Ans: √
(x) If one angle of a parallelogram is right angle, then it is a rectangle.
Ans: √
2. A parallelogram can be thought of as special trapezium, Give reason.
Ans: A parallelogram cannot be thoughts of as special trapezium, because both the pairs of opposite sides of a parallelogram are parallel and equal to each other, but in case of a trapezium one pair of opposite side are parallel and other two sides are slanting.
3. All squares are rhombus. Give reason.
Ans: All sides and all angles of a square are equal (each angle = 90°), on the other hand all sides of a rhombus are equal. That is why we can say that all squares are rhombus.
4. All rhombuses are parallelogram, but all parallelograms are not rhombus. Give reason.
Ans: Both the pairs of opposite sides of a parallelogram are parallel and equal to each other. All the sides of a rhombus are equal. Thus all rhombus are parallelogram but all sides of a rhombus are equal, not parallel. So, all parallelogram are not rhombus.
