Question

If r is the set of isosceles right angle traingles and i is set of isosceles triangle, then
(a) R=1 (b) RƆ1 (c)RC1 (d) none of the above.

Answer 1

Answer:

If r is the set of isosceles right angle traingles and i is set of isosceles triangle, then

(a) R=1

(b) RƆ1

(c)RC1

(d) none of the above.

Answer 2

The correct answer is c) R⊂I when R is the set of a right-angled isosceles triangle and I is the set of the isosceles triangle.

• Isosceles triangles are a type of triangle whose two sides tend to be equal.
• Whereas, in the case of the isosceles triangle which is a special case of an isosceles triangle, two sides of the triangle remain equal with one angle of the triangle is 90°.
• In such a case, we can easily understand that right-angled isosceles triangles are a special case of the isosceles triangle. Thus they fall under the category of the isosceles triangle.
• Therefore, all right angles isosceles triangles are isosceles triangles but all isosceles triangles are not right-angled isosceles triangles.
• Thus the set R becomes the subset of I. Thus, the correct option is c)R⊂I
