Yes
The answer depends on their relative sizes and configuration.
An acute triangle can be an isosceles triangle, but it doesn't have to be. An isosceles triangle can be an acute triangle, but it doesn't have to be.
isosceles triangle
A right triangle and an isosceles triangle have the fact that they are both triangles in common. A right triangle can also be an isosceles triangle.
An isosceles triangle is a triangle that has two equal sides.
Are isosceles triangle sometimes an equilateral triangle
You cannot. An isosceles triangle cannot be scalene and a scalene triangle cannot be isosceles. So an isosceles scalene triangle cannot exist.
NO!!! A triangle is a 2-dimensional shape of three sides; archaically a 'trigon'. A polyhedron is a 3-dimensional solid of many sides.
how is an isoscelels trapezoid related to a isosceles triangle
An obtuse triangle is not necessarily isosceles, but it can be.
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
A triangle that has one right angle and is isosceles is called an isosceles right triangle.
