Using angles and sides:
Using angles only:
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.
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.
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.
You need enough information about both triangles to be able to compareany one of the following packages of parts of both of them:-- the length of any two sides and the size of the angle between them-- the size of any two angles and the length of the side between them-- the lengths of all three sides.
no because it has to be all equal and right angles
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
pentagon
For equal sides make an Equilateral triangle. Equilateral triangles have 3 internal angles of 60o. All 3 sides are equal length. Make one using those characteristics.
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.
Using the cosine formula for triangles the opposite angles of the given sides are 88.05 degrees, 39.93 degrees and 52.02 degrees respectively all rounded to two decimal places.
Triangles total 180 degrees. Triangles have three angles. Two angles of 90 degrees total 180 degrees.
Triangles can be drawn in various shapes and sizes but they all have 3 sides and 3 interior angles that add up to 180 degrees.
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.
All isosceles triangles: - Have angles that add up to 180 degrees - Have two equal sides. The unequal side is called the base. - Have equal base angles. - Have areas and perimeters that can be found using the formulas Area=1/2 X (base X height) and Perimeter=side+side+side An equilateral triangle with a right angle is called a right isosceles triangle. Also, all equilateral triangles are isoceles triangles, but not all isosceles triangles are right triangles.
