WebSo, it is not a right triangle. iv.Given that sides are 13 cm, 12 cm, and 5 cm. Squaring the lengths of these sides we may get 169, 144, and 25. Clearly, 144 +25 = 169 Or, 12 2 + 5 2 = 13 2. Therefore given triangle is satisfying Pythagoras theorem. So, it is a right triangle. The longest side in a right angled triangle is the hypotenuse. WebFor a given triangle to be a right angled, the sum of the squares of the two sides must be equal to the square of the largest side. (i) Let a = 9cm, b = 16 cm and c = 18 cm. Then . Hence the given triangle is not right angled. (ii) Let a = 7cm, b = 24 cm and c = 25 cm, Then . Hence, the given triangle is a right triangle.
In a triangle ABC, right angled at B, AB=24cm, BC=7cm.
WebPQRA is a rectangle, AP = 22cm, PQ = 8cm. ∆ ABC is a triangle, whose vertices lie on the sides of PQRA such that BQ = 2cm and QC = 16cm .Then the length of the line joining the mid points of the sides AB and BC is a. 4 2 cm b. 5 cm c. 6 cm d. 10 cm (b) 81. ∆ ABC is an isosceles right angled triangle having ∠ C = ° 90 . If D is any point ... WebApr 15, 2024 · We start with a right angled triangle ABC, such that angle ABC = beta and angle BAC = alpha. We label sides BC = a, CA = b and AB = c. Next we draw a congruent triangle ACD. We then draw the perpendicular line to AB through point B and we also extend the line AD until it meets this perpendicular at E. ...
