WebMay 6, 2012 · If it is a right angle triangle, with B the right angle, cos B = cos 90o = 0 and this becomes Pythagoras making the side: b = √218 cm. ≈ 14.76 cm. If there is a right angle, not between the 7 cm and 13 cm, then the 13cm side is the hypotenuse (as the hypotenuse must be the longest side) and the other side is: b = √ (132 - 72) cm.

WebA triangle can be classified using the third angle. 5. When all of the angles of a triangle are congruent, the triangle is equiangular. Sides: AB,BC,CA Vertices: A, B, C Angles: ∠BAC or ∠A, ∠ABC or ∠B, ∠BCA or ∠C In an acute triangle, all the angles are acute. In an obtuse triangle, one angle is obtuse. In a right triangle, one WebNov 20, 2024 · Divide the length of the shortest side of the main triangle by the hypotenuse of the main triangle. Multiply the result by the length of the remaining side to get the length of the altitude. Alternatively, the angles within the smaller triangles will be the same as the angles of the main one, so you can perform trigonometry to find it another way. WebWe know that BD is the angle bisector of angle ABC which means angle ABD = angle CBD. Now, CF is parallel to AB and the transversal is BF. So we get angle ABF = angle BFC ( alternate interior angles are equal). But we already know angle ABD i.e. same as angle ABF = angle CBD which means angle BFC = angle CBD. forsters legal cheek
