How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
What is an acute triangle?
A triangle with an acute angle.An acute triangle has all three angles less than 90 degrees.
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.
What is a polygon with 3 sides 2 acute angles and 1 right angle?
Oh honey, that's a sassy little shape called a scalene triangle. It's got three sides of different lengths, two acute angles (less than 90 degrees), and one right angle (90 degrees). It's like the rebellious teenager of the triangle family.
Does a triangle have a square corner?
A triangle can have a corner of any measure greater than zero and less than 180 but the three angles must add up to 180 degrees.
