Problem 149
Decide if the following statement is true”
A right triangle cannot be an obtuse triangle.
Explain why or why not?
Solution
Yes , a right angle can’t be an obtuse triangle because in triangle sum of angles
are 180° and one angle is 90° in right angle so sum of rest two angles are
(180-90)=90° so there will not any angle more than 90° so no
obtuse triangle.
