 Welcome to the session. Let's start the session with a question. Construct an isocialist right angle triangle ABC where pressure of angle ACB is 90 degree and AC is equal to 6 centimeter. Let us first understand the definition of isocialist right angle triangle. Now this is a triangle in which heights are equal. The idea behind our question will take the help of this key idea to solve the above question. So let's start the solution. Measure of CB is equal to 90 degree and AC is equal to 6 centimeter. So this implies this is also equal to 6 centimeter because we have to construct an isocialist right angle triangle. You know that in an isocialist right angle triangle two sides are equal and one angle is of 90 degree. Now we will start stepwise for the given construction. So first step is draw a rough sketch with given measures. This is a rough sketch with given measures where angle ACB is 90 degree, AC is 6 centimeter and CB is also equal to 6 centimeter. Now we will start the actual construction with the help of this rough sketch. Draw a line that meant CB of length 6 centimeter according to our rough sketch to draw CX perpendicular to CB. So our next step is C draw CX perpendicular to CB. A should be somewhere on this perpendicular according to our rough sketch. We see that from C the point A is at a distance of 6 centimeter. So our next step is with C is center draw an R of radius 6 centimeter this point on this perpendicular CX. Our next step is join AB triangle ABC is now obtained where the measure of angle C is 90 degree and AC is equal to BC is equal to 6 centimeter. So this completes our session. I hope you have enjoyed the session. Bye and take care.
