Use a protractor and they are classified as follows:-
Acute angle: which is greater than 0 but less than 90 degrees
Right angle: which is 90 degrees
Obtuse angle: which is greater than 90 but less than 180 degrees
Reflex angle: which is greater than 180 but less than 360 degrees

How does the measure of an angle help you classify shapes?
In triangles the angles can be all sorts of measurement but the three angles always add to 180 degrees. In quadrilaterals the angles usually measure to 90degrees in all four corners. But in things line trapezoids and parallelograms the angles differ. In a pentagon the angles are 120 degrees. All five of them.
What are the four ways to classify triangles by angle measure?
You can classify triangles by:Whether one of their angles is greater than 90 degrees, equal to 90 degrees, or all angles are less than 90 degreesWhether they have two or three congruent angles (equivalent to having two or three congruent sides)I think that's about it.
What do you write when classifying triangles?
there is many ways to write when classifying a triangle, you can classify it by its sides or angles. When you classify it by angles you can classify it by acute, obtuse, and right triangle. when classyfing it by sides its isosceles, equilateral, and scalene!
Are congruent angles angles that have measure?
Yes, congruent angles are angles that have the same measure.
Angles that have the same measure are?
Angles with the same angle measure are congruent.

How do you classify a quadrilaterals?
You classify a quadrilateral by its sides, angles, and its vertices.

Yes, congruent angles are angles that have the same measure.
How do you classify a triangal by its sides?
Three identical angles.
What are three ways to classify a triangles by its angles?
The three kinds of triangles are:right triangle :one of the angles is a right angle (i.e. measures 90 degrees)acute: All of the angles measures less than 90 degrees. A special case of acute isthe equiangular or equilateral triangle in which all angles measure 60 degrees;obtuse: One of the angles measure more than 90 degrees.
What instrument used to measure angles?
use a protractor to measure angles
What Is The Unit Used To Measure Angles.?
Degrees are used to measure angles.
Angles that have the same measure are?
Angles with the same angle measure are congruent.
If two of a triangle angles measure 42 degrees 48 degrees how would you classify that triangle?
acute , obtuse obtuse or right angle
How would you classify pairs of opposite angles in a parallelogram?
As equal or congruent.
