This post covers all the Area Questions on Right Angled Triangle
Right Angle Triangle follows following formula:
The square of Hypotenuse is the sum of square of other two sides.
This formula is important as it will help us to solve different problems, so please remember it.
Also, the formula for the area of right angled triangle is given as:
The sides of a triangle are 3 cm, 4 cm, and 5 cm. The areas (in sq.cm) of the triangle formed by joining the mid- points of the sides of this triangle is?
Since the triangle satisfy above condition, it is a right angled triangle
Area = ½ *base * height
= ½ * 4 *3
= 6 sq cm.
As you can see in the figure above, the triangle formed by joining midpoint is one fourth of the main figure.
(△DEF) =1/4×6 =3/2 sq cm.
Hence 1.5 sq-cm is the answer
