Which type of triangles has exactly two sides that are congruent?
An Isosceles triangle has two sides (and two angles) congruent.
How many sides does an isosceles triangle have that are congruent?
An isosceles triangle has exactly two sides which are equal. (The word congruent usually applies to triangles, not sides.)
How many different isosceles triangles have at least one angle that measures exactly 20?
If one angle measures 20 degrees then the other two angles must each measure 80 degrees and many other similar or congruent isosceles triangles can have the same interior angles.
Equilateral triangle has one angle that is exactly 90 degrees?
An equilateral triangle is a special isosceles triangle in which all three sides are congruent. Equilateral triangles are also equiangular, which means all three angles are congruent. The measure of each angle is 60 degrees.
What is a triangle with exactly 2 congruent angles?
isosceles
Which type of triangles has exactly two sides that are congruent?
An Isosceles triangle has two sides (and two angles) congruent.
Are all isosceles triangles with two 50 degrees and exactly one side of length 10cm congruent?
Yes, they are.
How many sides does an isosceles triangle have that are congruent?
An isosceles triangle has exactly two sides which are equal. (The word congruent usually applies to triangles, not sides.)
How many different isosceles triangles have at least one angle that measures exactly 20?
If one angle measures 20 degrees then the other two angles must each measure 80 degrees and many other similar or congruent isosceles triangles can have the same interior angles.
Equilateral triangle has one angle that is exactly 90 degrees?
An equilateral triangle is a special isosceles triangle in which all three sides are congruent. Equilateral triangles are also equiangular, which means all three angles are congruent. The measure of each angle is 60 degrees.
What are triangles with at least two congruent sides?
A triangle with two congruent sides is an isoscelestriangle. But an equilateral triangle has two congruent sides. (It actually has three congruent sides.) And isosceles triangle is generally described as a triangle with exactly two congruent sides.
Can you make 2 exact triangles using exactly 9 toothpicks?
If one of the nine toothpicks is the common base of the two congruent isosceles triangles with sides formed by two toothpicks.
If triangle ABC is congruent to triangle bcd then triangles ABC and bcd are what kinds of triangles?
The 2 triangles can be of any type (e.g isosceles, equilateral, etc.), only they must be exactly the same if they are congruent, i.e one triangle must be an exact copy of the other one.
Polygon with exactly two sides congruent?
Isosceles
What is a triangle with exactly 2 congruent angles?
isosceles
Does an isosceles triangle have exactly 2 lines of symmetry?
No, isosceles triangles only have one. ■
All equilateral triangles are also isosceles triangles?
True or False, depending on your definition of isosceles triangles!Actually, whether your answer is true or false depends upon your definition of an isosceles triangle. Some mathematicians define an isosceles triangle as one with at least two sides, while others define an isosceles triangle as one with exactly two sides. The latter definition is the more generally accepted one. Since an equilateral triangle has three, not exactly two congruent sides, people using the second definition of isosceles triangles would say that the statement is false, not true.False because an equilateral triangle has 3 equal sides whereas an isosceles triangle has only 2 equal sides
