How do you find the length of the altitude to the base when an isosceles triangle has the base nagles of 30 degrees and base measures 12?
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
What is the degrees of an acute isosceles triangle?
101 degrees :p
What is a isosceles right triangle?
In an isosceles right angled triangle,1 angle is 90 degrees and the other two are equal ,each is 45 degrees
Which triangle is not an isosceles triangle?
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.
Can a right triangle be isosceles?
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.

A triangle with two congruent sides and an angle of 104 degrees is?
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.
