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

If one angle of an isosceles triangle measures 60 degrees then the triangle is equilateral?
yes
What are the measures of the base angles of a right isosceles triangle?
45 degrees.
What is the measure of the base angle of an isosceles triangle if the vertex measures 38 degrees?
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
What is a triangle that has angles that measures 45 45 90 degrees?
It is an isosceles triangle. 45 + 45 + 90 = 180 degrees
How do you find the measures of the angles in a right isosceles triangle?
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
What type of triangle has an angle that measures 120 degrees and an angle that measures thirty degrees for kids?

An isosceles triangle that is not an equilateral triangle?
It is possible if neither of the angles in the triangle measures to 60 degrees
If one angle of an isosceles triangle measures 60 degrees then the triangle is equilateral?
yes

62 degrees
What are the measures of the base angles of a right isosceles triangle?
45 degrees.
What is the measure of the base angle of an isosceles triangle if the vertex measures 38 degrees?
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
What is a triangle that has angles that measures 45 45 90 degrees?
It is an isosceles triangle. 45 + 45 + 90 = 180 degrees
What type of triangle has an angle that measures 100 degrees and an angle that measures 50 degrees?
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
How do you find the measures of the angles in a right isosceles triangle?
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
A triangle that measures 45 45 90 degrees is?
isosceles right angle traingle
What are the measures of all the angles in an isosceles right triangle?
They are: 45, 45 and 90 degrees
What type of triangle has an angle that measures 120 degrees and an angle that measures thirty degrees?
An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
