How can a triangle be classified in two ways?
You can classify a triangle by its sides, or by its angles.To classify a triangle by its sides:1- A triangle with three sides that are equal in length is called an equilateral triangle.2- A triangle with two sides of the same length and one different is called an isosceles triangle. 3- A triangle with no sides of equal length is called a scalene triangle. To classify a triangle by its angles: 1- A triangle with three angles that are greater than 0 and less than 90 degrees is called an acute triangle.2- A triangle with one angle that is 90 degrees exactly is called a right angle triangle.3- A triangle with one angle that is greater than 90 degrees is called an obtuse triangle.
How do you classify triangles using their attributes?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and are classified as follows:- Scalene triangle has 3 different acute angles Obtuse triangle has an obtuse angle and 2 different acute angles Right angle triangle has a 90 degree angle Isosceles triangle has 2 equal sides and 2 equal base angles Equilateral triangle has 3 equal sides and 3 equal 60 degree angles
If two angles in a triangle are congruent to two angles in another triangle then the angles are also congruent.?
If two angles in a triangle are congruent to two angles in another triangle, then the ______________ angles are also congruent.
A triangle that has three 3 acute angles is a what?
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
How do you classify a quadrilaterals?
