An equilateral triangle. * * * * * An isosceles triangle.
What kind of triangle has two sides of equal length?
An isosceles triangle is a triangle that has two sides of equal length.
What type of triangle can an isosceles triangle be scalene right acute obtuse?
What are the properties of the various triangles given:Isosceles triangles have two sides equal, two angles equalScalene triangles have all three sides different and all three angles differentRight triangles have one angle which is a right angle (90°)acute triangles have all angles less than 90°obtuse triangles have one angle greater than 90°As an isosceles triangle has two sides equal, it cannot be a scale triangle which has all three angles different.For the other three properties, consider:The sum of the angles in a triangle is 180°If one angle is 90°, the other two angles could be: (180° - 90°) / 2 = 45° each - two angles the same→ an isosceles triangle could be a right triangleIf all angles are less than 90°, let one angle be 80°, the other two angles could be: (180° - 80°) / 2 = 50° each - two angles the same→ an isosceles triangle could be an acute triangle(Note that if one angle was 60°, then the other two being equal would be: (180° - 60°) / 2 = 60° each making all three angles the same and the triangle an equilateral triangle)If one angle is greater than 90°, let it be 100°, the other two angles could be: (180° - 100°) / 2 = 40° each - two angles the same→ an isosceles triangle could be an obtuse triangleFrom the given list, an isosceles triangle could be a right, acute or obtuse triangle, but it could not be a scalene triangle.
A Triangle that has 2 sides of equal length?
A triangle with two equal sides and two equal angles is called an isosceles triangle.
If two angles in a triangle are congruent to two angles in another triangle what can you conclude about the third angle on both triangles?
Equilateral Triangle
What are two special properties of a 45-45-90 triangle?
It is a right angle triangle and it is also an isosceles triangle
Properties of scalene triangle?
what is a properties of scalene triangle
What are 2 properties of an isosceles triangle?
-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's base.
Properties of a scalene triangle?
properties of a scalene
Properties of a triangle?
a triangle has 3 sides, verticies
What are the properties of a right-angle triangle?
A right triangle has one right angle and two acute angles. Right triangles have a hypotenuse and also two legs. You can use the Pythagorean Theorem to find the hypotenuse, or the two legs of the right triangle, as long as you have the side lengths of the other two sides on the right triangle.
What are the properties of obtuse angled triangle?
It has one obtuse angle. It must, therefore, have two acute angles.
Why was the triangle invented?
The triangle was not invented. It is the result of observations of physical properties.
What are the properties of a quadrilateral triangle?
There is no such thing.
Are all right triangle and equilateral triangle similar?
No because a right angle triangle has different properties to an equilateral triangle
Can a triangle be classified as an equilateral triangle?
No not ever because they both have different properties
What are the properties of a semi circle?
triangle form in a semi circle is right triangle
