Question

draw a right angle triangle​

Answer 1

Let us construct a right-angled triangle ABC, right-angled at C. Consider the length of the hypotenuse AB = 5 cm and side CA = 3 cm. The steps for construction are:

Step 1: Draw a horizontal line of any length and mark a point C on it.

Step 2: Set the compass width to 3 cm.

Step 3: Place the pointer head of the compass on point C and mark an arc on both the sides of C.

Step 4: Mark the points as P and A where the arcs cross the line.

Step 5: Set the compass width to the length of the hypotenuse, that is, 5 cm.

Step 6: Place the pointer head of the compass on point P and mark an arc above C.

Step 7: Repeat step 6 from point A.

Step 8: Mark the point as B where the two arcs cross each other.

Step 9: Join the points B and A as well as B and C with the ruler.
