Why cant there be a obtuse angle in a right triagle?
A triangles angles must add up to 180 degrees, no more or less
Can a right triangle also be an isosceles triagle?
Yes
Lines of simitry in a scalen triagle?
a 3 side shape.
Can you draw a scalene obtuse triangle explain?
Yes, it's quite simple. First, let's define what a scalene obtuse triangle is and in so doing show that a scalene obtuse triangle CAN be constructed.'Scalene' means that all three sides are not equal (of different lengths).'Obtuse' means that at least one of the angles is greater than (>) 90o.So, as long as the triangle has 3 sides that are not equal and contains one angle that is >90o, you can create a scalene obtuse triangle.Another way to make sure you can construct the aforementioned is:If you know the lengths of the triagle sides you can add any two(2) of them the sum of which should be greater than the length of the 3rd side. This is know as the Triangle Inequality Theorem.Under the Resources link, there is a website to construct a scalene obtuse triangle as proof.
