A right triangle ABC right angled at A with lengths of perpendicular sides 4 cm and 3 cm is constructed. Keeping the third side as the base, another triangle BCD is constructed such that ∠DBC = 40∘ and ∠BCD = 30∘. Then the perimeter of triangle BCD is
Question 7
Lengths of sides of a triangle are 3 cm, 4 cm and 5 cm. The triangle is
a) Obtuse-angled triangle b) Acute angled triangle c) Right angled triangle d) An isosceles right triangle.
In a right angled triangle, if the length of sides are 3 cm and 4 cm, then the length of hypotenuse is
