What is the pattern linking the number of sides to the number of triangles?
number of sides minus 2 = number of interior triangles
How many triangles does a polygon have?
It varies regarding the number of sides of polygon.Additional Information:-The formula is for any polygon: n-2 = number of interior triangles whereas n represents the number of sides of the polygon
What is a polygon with eight sides and eight interior triangles?
Octagon
How do you divide a polygon into triangles to find the sum of its interior angles?
If a regular polygon has n sides, then the number of triangles in that polygon is n - 2. thus, the sum of its interior angles is equal to (n - 2)180°.
Why do triangles have 180 degrees?
Because the formula for the interior degrees of a polygon is (number of sides -2)*180 = sum of interior angles. A triangle has 3 sides so: (3 -2)*180 = 180 degrees
Number of triangles in a 32 side polygon?
gghg a regular polygon has a 32 sides. calculate the size of each interior angle.
How many triangles in an undecagon?
There are 11 triangles in an undecagon. The number of sides of a polygon is the number of triangles it has.
Kinds of triangle according to number of congruent sides?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees. Equilateral triangles have 3 congruent sides. Isosceles triangles have 2 congruent sides. A right angle triangle can have 2 congruent sides if its interior angles are 90, 45, 45 degrees. A scalene or an obtuse triangle has no congruent sides.
What are equivalent triangles?
They are triangles with 3 equal sides and 3 equal interior angles or triangles that are congruent in shape
Are two equilateral triangles sometimes always or never similar to each other?
Since triangles have three sides and must have interior angles equal to pi or 180o, the three interior angles in all equilateral triangles will be pi/3 or 60o.However, equilateral triangles must also have equal side lengths. Since equilateral triangles with interior angles of 60o will not necessarily have the same side lengths, two equilateral triangles will sometimes be similar to each other.
IS THERE a relationship between the number of sides of the polygon and the interior angles?
Yes, they are the same. Triangles have 3 sides and 3 angles. Squares have 4 sides and 4 angles. Octagons have 8 sides and 8 angles.
How are triangles different from quadrilaterals l be specific?
Triangles have 3 sides and 3 interior angles that add up to 180 degrees Quadrilaterals have 4 sides and 4 interior angles that add up to 360 degrees
