Choose the correct one. 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

A triangle with all its sides of unequal lengths is called a - scalene triangle.

(i)No, because sum of two acute angles is less than 180°.  (ii) No, because sum of two obtuse angles is more than 180°.  (iii) Yes, because sum of two right angles is...

Correct answer is (d) 4

Correct answer is (c) acute

Correct answer is (d) Difference of any two sides of a triangle is greater than the third side

Correct answer is (c) 3 cm and 16 cm

Correct answer is (b) 4 cm

Correct answer is  (b) AC2 = AB2 + BC2

If hypotenuse and an acute angle of one right triangle are equal to the hypotenuse and an acute angle of another right triangle, then the triangles are congruent. True

Hi Can you tell me, why did you square both sides?
