Scalene right angled triangle
One right angle
Two other unequal angles
No equal sides .
⇒ take base 3cm
mark line segment as a and b
⇒ now a as center measure 90 degrees
⇒a as center draw up to 4 cm then as mark as c
now join c and b
now it is scalene right angled triangle.
ab = 3cm , ac = 4 cm , bc = 5 cm and angle a is 90 degrees
hence Δ abc is scalene right angled triangle.
