It is always isosceles because it can be proved as follows:
The perpendicular bisector dissects the triangle into two, and it is the common side. Then each side of the bisector is 90 degrees, and the bisected to two equal sides, so the two dissected triangles are congruent, hence the original triangle is isosceles.
Answer: 36
Step-by-step explanation:
(Triangle ABC is isosceles)
(base angles of an isosceles triangle are congruent)
(In triangle CMB, angles in a triangle add to 180 degrees)
(triangle sum theorem)
(30-60-90 triangle CMB)
(sides opposite congruent angles in a triangle are congruent)
(segment addition postulate)
Answer:
Explanation:
Assuming the correct expression is to find the following limit:
Use the property the limit of the quotient is the quotient of the limits:
Evaluate the numerator:
Evaluate the denominator:
- Since
In order to calculate the area of a triangular prism, You can use the formula,
Area = 1/2 * a * c * h
