all the parts answers...... and also has to make false statement true
Answers
Answer:
A. TRUE
B. TRUE
C. TRUE
D. FALSE
E. FALSE
Step-by-step explanation:
Given some statements we have to tell these are true are false.
Statement (a): All the angles of triangle can be acute.
As, acute triangles has all angles acute.
Hence, TRUE
Statement (b) : It is possible to have right isosceles triangle.
As, if one of the angle of triangle is of 90° and other two are of 45° then we get a right isosceles triangle.
Hence, TRUE
Statement (c): The sum of any two sides of triangle is greater than or equal to third side.
As, by the Triangle Inequality Theorem which states that the sum of any 2 sides of a triangle must be greater than the measure of the third side..
Hence, TRUE
Statement (d) : The sum of any two angles is always greater than the third angle.
As, in any right-angled triangle one angle is 90 degrees, so the other two angles must have a sum of 90 degrees. Hence, not greater its equal.
Hence, FALSE.
Statement (e) : The square of hypotenuse of a right angle is equal to the sum of other two sides.
As, Pythagoras theorem states that the square of hypotenuse of a right angle is equal to the sum of square of other two sides.
Hence, FALSE
