Name each of the following triangles in two different ways: (you may judge the nature of the angle by observation) (a) (b) (c) (d) (e) (f)

Answer:

By observing the given triangles in two different ways, name of each triangle is as given below (a) In the given triangle, two sides are equal, so it is an isosceles triangle and all the angles are acute angles. So, it is an acute angled triangle alSol. (b) In the given triangle, all the sides are different, so it is a scalene triangle and one angle is right angle. So, it is a right angled triangle alSol. (c) In the given triangle, two sides are equal, so it is an isosceles triangle and one angle is an obtuse angle. So, it is an obtuse angled triangle alSol. (d) In the given triangle, two sides are equal, so it is an isosceles triangle and one angle is right angle. So, it is a right angled triangle alSol. (e) In the given triangle, all the sides are equal, so it is an equilateral triangle and all the angles are acute. So, it is an acute angled triangle alSol. (f) In the given triangle, all the sides are different, so it is a scales triangle and one angle is an obtuse angle. So, it is an obtuse angled triangle alSol.
