Yes, some triangles will have what in math they call a "Hidden angle." These will contain 3 regular angles adding up to 180 degrees and an additional angle with a maximum degree of 87. To calculate the hidden angle the most ethical approach is to use the Tangent Law.

How many triangles are in a pentagon and how many sides?
A pentagon has 3 triangles and 5 sides
What is a triangle called with 2 congurent sides?
isosceles triangles have 2 congruent sides scalene triangles have no congruent sides equilateral triangles have 3 congruent sides
Are all equilateral triangles are congruent?
no. if one triangles sides are all 2 and one triangles sides are all 3 then they are not congruent
What is the name of the triangle that has 3 equal sides?
Triangles with three equal sides are called equilateral triangles.
Are Some triangles are quadrilaterals?
Well, first of all triangles can't be quadrilaterals because qaud means four and tri means 3. A triangle is a polygon. A triangle can not have any less or any more than 3 sides, but not all of them have to be the same length, so therefor it can defenitally not be a quadrilateral because it only has 3 sides and it doesn't have to be equal on all of the sides.
How do you classify triangles by their sides and br their angles?
Classification of triangles by their sides:equilateral = 3 sides are equalisosceles = 2 sides are equalscalene =no equal sideClassification of triangles by their angles:acute = the 3 angles are less less than 90 degreesright = it has an angle which is 90 degreesobtuse = it has an angle which is more than 90 degrees
Which types of triangles can have 2 or more sides with equal lengths?
All triangles have 3 sides but an isosceles triangle has 2 equal sides and an equilateral triangle has 3 equal sides.
How many triangles are in a pentagon and how many sides?
A pentagon has 3 triangles and 5 sides
What kind of triangles have 2 sides?
None because all triangles have 3 sides
What have 3 sides?
Triangles
How many congruent sides are in an equilateral triangle?
3 because equilateral triangles are triangles that have 3 congruent sides.
What is a triangle called with 2 congurent sides?
isosceles triangles have 2 congruent sides scalene triangles have no congruent sides equilateral triangles have 3 congruent sides
Does a triangle have 2 congruent sides?
Some, but not all. Triangles with 2 congruent sides are called isoceles triangles. Triangles with 3 congruent sides are called equilateral triangles.
A type of triangle with no equal sides?
There are three types of triangles. Scalene triangles have no congruent sides or angles, equilateral triangles have 3 congruent sides and 3 60degree angles, and isosceles triangles have two congruent sides and two congruent angles.
Are all squares triangles?
No because squares have 4 sides whereas triangles have 3 sides
How are equilateral triangles and isosceles triangles different?
Equilateral triangles have 3 equal sides whereas isosceles triangles have only 2 equal sides
How many sides isosceles triangles has?
All triangles have exactly 3 sides. That is what the word triangle means, a geometrical figure having 3 angles and 3 sides. Always 3.
