Treat it as being two right angled triangles by halving the base and use the cosine ratio to find its hypotenuse (which will be one of the equal sides) cosine = adjacent/hypotenuse hypotenuse = adjacent/cosine hypotenuse = 6/cosine 20 degrees = 6.385066635 The length of the equal sides = 6.4 units correct to one decimal place.
An isosceles triangle is any triangle with at least two sides of equal length. Logically, an isosceles triangle also has at least two angles of equal size. An equilateral triangle is a triangle with three equal sides and three equal angles (all of which are 60 degrees). Since it has at least two equal sides then it is therefore also an isosceles triangle. This is no different to the way in which a square is also a rectangle, or a circle is also an ellipse. They are simply special cases of the general case.
All triangles have a total of 180 degrees. In an isosceles triangle the two angles opposite the side of equal length will have equal degrees.
A right angle triangle is a triangle with an angle 90 degrees. An isosceles triangle is a triangle with two or more equal angles/ length of lines. An equilateral triangle can also be an isosceles triangle.
In an isosceles triangle, two of the interior angles have the same number of degrees. This is because an isosceles triangle has two sides of equal length, which means the two base angles (the angles opposite those equal sides) are congruent. The third angle, called the apex angle, can be different from the base angles unless the triangle is also equilateral.
Equilateral triangle has all three sides of equal length and all three angles are equal. Isosceles only has two sides of equal length and two of the angles are equal.the equilateral triangle has 3 equal sides and a isosceles triangle has 2 equal sides. that should help
The triangle with angles measuring 50 degrees, 65 degrees, and 65 degrees is an isosceles triangle. In an isosceles triangle, two of the three angles are equal, making it a special type of triangle. In this case, the two angles measuring 65 degrees are equal, indicating that the two sides opposite these angles are also equal in length.

The angles inside any triangle sum to 180 degrees. Isosceles simply means two sides are the same length.
In the equilateral triangle, all the sides are the same length and all the angles are the same size (congruent). Since the sum of the angles of a triangle is always 180 degrees, we can figure out the measure of the angles of an equilateral triangle.Another Answer:-An isosceles triangle has 2 equal base angles plus another angle and the 3 interior angles add up to 180 degrees.
An isosceles triangle has 3 sides 2 of which are equal in length and 3 interior angles that add up to 180 degrees 2 of which are equal in size
Equilateral triangle has all three sides of equal length and all three angles are equal. Isosceles only has two sides of equal length and two of the angles are equal.the equilateral triangle has 3 equal sides and a isosceles triangle has 2 equal sides. that should help
No, an obtuse triangle cannot be isosceles. An isosceles triangle has two sides that are equal in length, but in an obtuse triangle, the angles are all greater than 90 degrees. Therefore, the sides cannot be equal in length.
It is an isosceles triangle and the other 2 angles will each measure 40 degrees
180 - (30 + 30) ie 120o
