In a right triangle abc in which angle b 90
WebThe sides that form the right angle are called legs. The hypotenuse is the longest side of the right triangle. Since the measure of a right angle is 90°, and since the sum of the three angles in any triangle equals 180°, the sum of the other two angles in a right triangle must be 180° - 90° = 90°, so they must be acute angles. Otherwise ... WebA right triangle with a ninety-degree angle, a twenty-degree angle, and seventy-degree angle. The side opposide of the twenty-degree angle is a units. The side opposite of seventy …

WebConstruct a right angle triangle ABC in which ∠B=90 ∘,BC=4cm and AC=5cm Medium Solution Verified by Toppr Steps of construction: (1) Draw a line segment XY. (2) Locate B, C on XY such that BC=4cm (3)Construct a line segment BD, sufficiently large, such that ∠B=90° (4)With C as centre and radius 5cm draw an arc, cutting BD at A; join AC. WebIf two triangles have two congruent angles, then the triangles are similar. So, if you have a 30-60-90 triangle then the sine ratio is defined as the ratio of the length of the side opposite to the length of the hypotenuse. Doesn't matter how "big" the triangle, those sides will always have the ratio of 1/2. ( 9 votes) Show more... rogirlash
