Does an acute triangle have two right angles?
No, in fact no triangle can have two right angles. The sum of all interior angles of any triangle is 180 degrees. All triangles must have three angles. A right angle is 90 degrees. So if a triangle has two ninety degree angles, there would be no third angle. An acute triangle has all three angles less than 90 degrees. The most common acute triangle is the equilateral 60-60-60 degree triangle.
Can a triangle have 2 acute angles?
yesss, because in an equilateral triangle all the angles are 60 degrees!! Most triangles have acute angles! :) xx
Why is triangle stronger than a rectangle?
Given unchanging lengths of the sides, a triangle cannot change its shape. But given unchanging lengths of the sides of a rectangle, it can change its shape by some force by changing its angle measurements. If a 2d load were put on a rectangle, enough force could squish the rectangle into a parallelogram, whereas a triangle cannot change shape without changing the lengths of its sides or bending its sides out of shape (most likely into a curve).Given these properties, a rectangle can collapse its shape much more easily and is flimsy compared to a triangle.
Find the measure of the third angle?
In euclidean (plane) geometry, the sum of the interior angles of any triangle is 180 degrees. Add the two angles you know (right angles = 90 degrees) and subtract that sum from 180. Without more information on the problem, that's the most I can assume
What is a 30 60 90 triangle?
A 30, 60, 90 triangle is a right triangle. It's one of the most common triangles to use to learn about the Pythagorean theorem.
