Question 61 Mark
Using the ruler, measure the lengths of seg AB and seg PQ. Are they of same length? Trace the seg AB on a sheet of transparent paper. Now place this new segment on PQ verify that if point A is placed on point P, then B falls on Q.
l(AB) = ___
l(PQ) = ___
Answer
View full question & answer→l(AB) = 4 cm
l(PQ) = 4 cm
Since the length of two segments is the same, if placed on one another, they will coincide.
l(PQ) = 4 cm
Since the length of two segments is the same, if placed on one another, they will coincide.
Question 71 Mark
Can a triangle be drawn if the three angles are given, but not any side? How many such triangles can be drawn?
Answer
View full question & answer→Yes a triangle can be drawn.
Since the length of side is not given, any length of side can be selected and then triangle can be constructed. We will get different triangles for different length of sides.
