Which triangle are two sides and two angles equal?
Every isosceles triangle. An equilateral triangle is a special case of an isoceles 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.
An equilateral triangle is a special case of a isosceles triangle?
Yes - if you define an equilateral triangle as one in which at least two sides are equal.
Does a rectangle and a triangle have special names?
rectangle is the "special name" of a shape with 4 corners (square). triangles are split in 3 groups. right triangle, one corner is 90 degrees equilateral triangle, every corner is 60 degrees isosceles triangle, two sides have the same length
How is an equilateral triangle an isosceles triangle?
An equilateral triangle, by definition, has three sides of equal length. The definition for an isosceles triangle is that it must have two sides of equal length, the other side being free to have any length. Based on these two definitions, we can say that an equilateral triangle is a special case of the isosceles triangle, namely one where the third side is also equal to the other two sides.
Which triangle are two sides and two angles equal?
Every isosceles triangle. An equilateral triangle is a special case of an isoceles triangle
What is a arbitrary triangle?
It is any triangle - one with no special characteristic - like a right angle, or two equal sides, etc.
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.
An equilateral triangle is a special case of a isosceles triangle?
Yes - if you define an equilateral triangle as one in which at least two sides are equal.
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.
Can an equilaterial triangle also be an isoseles triangle?
An isosceles triangle has two congruent sides, and An equilateral triangle is a special isosceles triangle in which all three sides are congruent.Therefore, all equilateral triangles are isosceles
How many equal angles dose an isosceles triangle have?
A isosceles triangle can have two equal angles, but an equilateral triangle is actually a special isosceles triangle, so it could also have 3.
What are the two properties of a triangle?
There are three sides and all internal angles add up to 180 degrees
What are the properties of obtuse angled triangle?
It has one obtuse angle. It must, therefore, have two acute angles.
Does a rectangle and a triangle have special names?
rectangle is the "special name" of a shape with 4 corners (square). triangles are split in 3 groups. right triangle, one corner is 90 degrees equilateral triangle, every corner is 60 degrees isosceles triangle, two sides have the same length

Based on these two definitions, we can say that an equilateral triangle is a special case of the isosceles triangle, namely one where the third side is also equal to the other two sides.
Can a triangle be a rhombus?
No, a triangle cannot be a rhombus. A triangle is a polygon with three sides, while a rhombus is a polygon with four sides of equal length. These two shapes have different properties and cannot be the same.
