Question

ABC is a right angled triangle,<B=90°,D is midpoint of AC,AB=3cm ,BC=4cm. what will be the measure of BD?​

Answer 1

Answer:

Step-by-step explanation:

By Pythagoras theorem AB^2 + BC^2= AC^2

(3)^2 + (4)^2 = x^2

9 + 16 = x^2

25 = x^2

X = 5

AC = 5cm

In a right angled triangle,the line which joins midpoint of hypotenuse from right angle is equal to distance between a point of hypotenuse to midpoint of hypotenuse.

BD = AD = CD

D divides the line into 2 equal parts

AD = 2.5cm

:. BD = 2.5 cm
