Are all triangles equilateral?
No.Equilateral triangles must have equal angles (all 60 degrees) and equal length sides; there are also:Isosceles triangles which have two equal angles and two equal sides;Scalene triangles which have all three sides, and hence all three angles, of different lengths;Right angled triangles (which can have all sides of different lengths, or two sides of equal length) have (as the name suggests) one right angle. This means Pythagoras and the trigonometric ratios can be used on its side lengths.
If 3 corresponding angles of two triangles are of equal measure are the side lengths of equal measure also?
Not necessarily. You have described "similar" triangles. If you also know that any of the lengths of sides are of equal measure in addition to three angles (congruent), then the lengths of all of the sides are of equal measure. But with what you have given, consider, for example, two equilateral triangles, both have all angles equal to 60 degrees (satisfying the condition in your question). One of the triangles could have sides length 1 and the other with sides all of length 2.
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
Are scalene triangles all obtuse?
No, a scalene triangle is simply a triangle where all angles are not equal and all side lengths are not equal, therefore they can or cannot be obtuse.
What are the different ways to classify triangles?
isosceles -2 equal sides, 1 other length side, 2 equal angles, 1 other angle scalene -all angles and sides different equilateral -all sides and angles same (angles always 60degrees)
Triangle has no equal anles or sides?
Equaliateral Triangles have all three sides and angles (60 degrees)equal Isosceles Triangles have to equal sides and angles Scalene Triangles have no equal sides or angles
Are triangles equilateral?
Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.
What is true about the angles and sides on similar triangles?
All the Angles and sides on Triangles are always going to equal 180 Degrees
What are the shapes that have 3 sides and 3 vertices?
The shapes that have 3 sides and 3 vertices are called triangles. Triangles are classified based on the lengths of their sides and the measures of their angles. The three most common types of triangles are equilateral triangles (all sides and angles are equal), isosceles triangles (two sides and two angles are equal), and scalene triangles (all sides and angles are different).
What are the two properties of congruent triangles?
All the corresponding sides in congruent triangles are equal All the corresponding angles in congruent triangles are equal
Are all triangles equilateral?
No.Equilateral triangles must have equal angles (all 60 degrees) and equal length sides; there are also:Isosceles triangles which have two equal angles and two equal sides;Scalene triangles which have all three sides, and hence all three angles, of different lengths;Right angled triangles (which can have all sides of different lengths, or two sides of equal length) have (as the name suggests) one right angle. This means Pythagoras and the trigonometric ratios can be used on its side lengths.
How do you classify triangles by angles and sides?
you classify triangles by seeing the sides as if the triangle was isosceles, equilateral, or scalene Isosceles= two angles equal or two sides equal Equilateral= all angles equal and all sides equal Scalene= all angles different and all sides different. ☻☻ I HOPE IT HELPED☻☻
If two triangles are congruent?
Then they both will be identical in sides and angles
What 2d triange has 2 equal sides and 2 angles?
An Isoceles triangle has two equal sides and two equal angles (though all triangles have three angles)
What does all the triangles look like and what type of triangle are they?
There are infinitely many types of triangles, and they can be classified according to their angles or sides (or both). Equilateral (equiangular triangles): All sides equal, all angles 60 degrees. Obtuse angled isosceles triangles: Two sides equal; one angle > 90deg. Right angled isosceles triangles: Two sides equal; angles of 90, 45, 45 degrees. Other isosceles triangle: Two sides equal; angles of 180-2x, x, x degrees. Obtuse angled scalene triangles: All sides unequal, one angle > 90 degrees. Right angled scalene triangles: All sides unequal, one angle = 90 degrees. Acute angled scalene triangles: All sides unequal, all angles < 90 degrees.
What are the diff kinds of triangles?
One way of classifying triangles is by the number of congruent sides (angles). A triangle is equilateral if all its sides are equal. All its angles will also be equal. A triangle is isosceles if two of its sides are equal. The angles at the end of the third side will be equal to one another. A triangle is scalene if all three sides are of different length. In this case, all three angles will also be different.
Are all equalateral triangles isosceles?
Yes. All equilateral triangles have three equal sides (or angles) so two of them MUST be equal.
