Using angles and sides:
- All three angles equal. This implies that all three sides are of the same length. The triangle may be known as an equiangular triangle but, more commonly, equilateral triangle.
- Two equal angles, which implies that two sides are equal. The triangle is an isosceles triangle.
- All three angles (and therefore sides) are different. This is known as a scalene triangle.
Using angles only:
- If all angles are less than 90 degrees it is an acute angles triangle.
- If one angle is 90 degrees, a right angled triangle.
- If one angle is greater than 90 degrees then an obtuse angled triangle.

How do i classify a polygon using their attributes?
The primary classification of a polygon is according to the number of sides (or vertices) that it has.If all the sides are of equal length and all the angles are of the same measure then it is a regular polygon.If any of the angles is a reflex angle then it is a concave polygon, otherwise it is convex.
How do you solve for triangle side lengths?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees. If you know the lengths of 2 sides of a triangle then the length of the 3rd side can be found by using trigonometry.
How do I classify polygons using their attributes?
The answer depends on what attributes you want to use for classification. These could be:number of sides (vertices),whether or not all sides are equal,whether or not all angles are equal,whether or not all sides and angles are equal (regular),number of parallel sides,number of perpendicular sides,order of rotational symmetry,number of lines of symmetry,convex or concave,various combinations of the above.
Is sam congruent del if so identify the similarity postulate or theorem that applies?
Yes, triangle SAM is congruent to triangle DEL if the corresponding sides and angles are equal. This can be established using the Side-Angle-Side (SAS) Congruence Postulate, which states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are congruent. Alternatively, if all three sides of both triangles are equal, the Side-Side-Side (SSS) Congruence Theorem can also be applied.
Is FGH JKL If so identify the similarity postulate or theorem that applies.?
Yes, triangles FGH and JKL are similar. The similarity can be established using the Angle-Angle (AA) postulate, which states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar. If the angles of FGH correspond to the angles of JKL, the triangles are indeed similar.
