The altitude is 12 cm and the area is 60 square cm.
Solved with the help of the trigonometrical sine ratio and Pythagoras' theorem.
An isosceles triangle can be considered as two right angle triangles joined together so use the tangent ratio to find its altitude: tan30 degrees = opp/6 (where opp is the altitude and 6 is half the base) 6*tan30 degrees = 3.464101615 units of measurement
101 degrees :p
In an isosceles right angled triangle,1 angle is 90 degrees and the other two are equal ,each is 45 degrees
An obtuse triangle or a right angle triangle. An equilateral is definitely an isoceles triangle * * * * * Not true. An obtuse or right angled triangles can be isosceles. It depends on the sizes of the two smaller angles. An isosceles triangle has two equal angles so a triangle with angles of size [A, (180-A)/2, (180-A)/2] degrees where 90 < A < 180 degrees would be an obtuse angled isosceles triangle. A triangle with angles of size (90, 45, 45) degrees is a right angled isosceles triangle.
No, an isosceles triangle can not be a right triangle, because a right triangle has an angle of 90 degrees angle, and two angles of 45 degrees. An isosceles triangle has all acute angles, therefor, making it an acute triangle, so no, an isosceles triangle is not, i repeat not, a right triangle.
because an isosceles triangle or any kind of triangle is 180 degrees.

a isosceles has 180 degrees
There is 180 degrees in every triangle.
Isosceles Triangle. An isosceles triangle is a triangle with (at least) two equal sides/ angles.
The right isosceles triangle has 180 degrees as all triangles do
a right triangle
It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.
An isosceles triangle has 3 interior angles that add up to 180 degrees, and 2 of its angles are equal and two of its sides are equal.
A triangle with two congruent sides is isosceles. A triangle with an angle of 104 degrees is obtuse. So you would have an obtuse isosceles triangle.
