CBSE - Herons Formula

1 Herons Formula 

In figure AE bisects <CAD and AE || BC then :

(1) D ABC is equilateral 
(2) D ABC is right angled
(3) D ABC is isosceles 
(4) D ABC is scalene triangle

2 Herons Formula 

In a right triangle one acute angle is double the other then the hypotenuse is :

(1) Equal to smallest side 
(2) Double the smallest side
(3) Triple the smallest side 
(4) None

3 Herons Formula 

Find the area of triangle whose sides are 24 cm, 26 cm and 10 cm :

(1) 120 cm² 
(2) 100 cm² 
(3) 60 cm² 
(4) 400 cm²

4 Herons Formula 

If D is the mid point of the hypotenuse AC of a right triangle ABC, then :

(1) BD = 1/2 AB 
(2) BD = 1/2 AC 
(3) BD = 1/2 BC 
(4) None

5 Herons Formula 

In a right angled triangle, the square of the hypotenuse is equal to twice the product of the other two sides. The acute angles of the triangle are :

(1) 30° and 30° 
(2) 30° and 60° 
(3) 15° and 75° 
(4) 45° and 45°
