 Hi and welcome to the session. Let us learn the construction of a right angle triangle when the lengths of one leg and its hypotenuse are given. That is RHS criterion. Let us construct a triangle A, B, C in which base B, C is equal to 4.8 centimeters, angle B is equal to 90 degrees and hypotenuse AC is equal to 6.2 centimeters. We will first of all draw a rough sketch of triangle ABC and mark all the measurements given. So here we have triangle ABC where the base BC is equal to 4.8 centimeters, angle B is equal to 90 degrees and hypotenuse AC is equal to 6.2 centimeters. Now let us construct the triangle ABC. Here we have given the base BC equal to 4.8 centimeters. So first of all let us draw a line segment BC of length 4.8 centimeters. So here we have line segment BC equal to 4.8 centimeters plus our first step of construction is draw line segment BC of length 4.8 centimeters. Now angle B is equal to 90 degrees so at point B let us draw an angle XBC equal to 90 degrees. So here angle XBC is equal to 90 degrees and thus second step of construction is at point B draw angle XBC equal to 90 degrees. Now CA is equal to 6.2 centimeters so with CA center and radius 6.2 centimeters draw an arc to cut way BX at point A like this. So this is the point A and our third step of construction is with CA center and radius 6.2 centimeters draw an arc to cut way BX at point A. Now join AC so here AC is equal to 6.2 centimeters thus triangle ABC is the required right angle triangle. So here we have constructed a right angle triangle ABC when the length of one leg BC and its hypotenuse AC are given. With this we finished this session hope you must have enjoyed it. Goodbye take care and keep smiling.
