That would be an isosceles triangle. Any triangle with two equal sides is isosceles. It also has two equal internal angles. The 100° angle can't be one of them because the internal angles of any triangle all add up to 180°. Your triangle has one internal angle of 100° and two internal angles of 40° each.
It is an isosceles triangle and the other 2 angles will each measure 40 degrees
we know that a triangle is 90 degrees by measuring its length or it can be known as right triangle which measures 90 degrees.
3Same answer with an explanation:In an equilateral triangle, all sides are the same length and all three interior angles have the same number of degrees (60 degrees each).
An equilateral triangle has 3 equal sides and 3 equal interior angles that add up to 180 degrees
An isosceles triangle is a triangle that has two sides of equal length. A right triangle has an interior angle of 90 degrees. A right isosceles triangle has both characteristics. The 90 degree angle will be the angle formed by the sides of equal length.
This is a right triangle.
Acute isosceles
It is an isosceles triangle and the other 2 angles will each measure 40 degrees
An equilateral triangle has 3 equal sides and 3 equal interior angles each measuring 60 degrees
we know that a triangle is 90 degrees by measuring its length or it can be known as right triangle which measures 90 degrees.
The 3 sides of an equilateral triangle are all equal in length and its 3 interior angles are equal in size each measuring 60 degrees
It doesn't matter what type of triangle it is, or the length of the sides. The sum of the interior angles of a triangle always adds up to 180 degrees
If you mean an equilateral triangle then it is a triangle with sides of equal length and interior angles of 60 degrees
3Same answer with an explanation:In an equilateral triangle, all sides are the same length and all three interior angles have the same number of degrees (60 degrees each).
It is a triangle whose 3 sides are equal in length and its 3 interior angles each measure 60 degrees
An isosceles triangle has 3 sides 2 of which are of the same length and it has 3 interior angles 2 of which are of the same size. Its 3 interior angles add up to 180 degrees.
If all angles in a triangle are equal to 60 degrees, then the triangle is an equilateral triangle. In an equilateral triangle, all three sides are equal in length. This property is a consequence of the triangle angle sum theorem, which states that the sum of the interior angles of a triangle is always 180 degrees. Therefore, if each angle is 60 degrees, the total sum of the angles in the triangle is 180 degrees, satisfying the theorem.
