So the question is is it acute, is it right, or is it obtuse. We must be talking about the other angle. So when we talk about acute, right, or obtuse, we can’t be talking about these angles Than hundred and eighty degrees for a triangle. If they were ninety degrees or more, then we’d have a sum of angles which is greater They’ve got to be less than ninety degrees. Now that means that this angle and this angle have each got to be acute. Remember the sum of the measures of the interior angles in a triangle is a hundred Now remember an acute angle is one which is between zero degrees and ninety degrees,Īnd an obtuse angle is between ninety degrees and one hundred and eighty degrees,Īnd a right angle is exactly ninety degrees. They’re the angles which are the angle where the sides of the same length meet. Now you should remember that the base angles in an isosceles triangle are equal, and Either it’s an acute isosceles triangle, a right isosceles triangle, or an obtuse Remember, scalene means that all the different sides of the triangle will beĭifferent lengths, so any triangle that says it’s a scalene triangle doesn’t match And triangles with two sides the same length are called isosceles triangles. And these little markers here and here tell us that those Well it’s an enclosed shape with three straight sides, so it is a triangle it’s a Isosceles triangle, c) right isosceles triangle, d) obtuse isosceles triangle, or e) Which of the following describes the given shape? a) acute scalene triangle, b) acute
