you can use the sine, cosine, tangent formula.
No, you do not need to know all the side lengths and angle measures to solve a triangle. You can solve a triangle using various methods, such as the Law of Sines or the Law of Cosines, if you have sufficient information, like two angles and one side (AAS or ASA), or two sides and the included angle (SAS). Additionally, having all three side lengths (SSS) is also enough to determine the triangle's angles.
You can't. You must know at least one length and at least two angles, or vice versa.
A triangle with one right angle and two acute angles is called a right triangle. In a right triangle, one of the angles measures 90 degrees, making it a right angle, while the other two angles are acute, meaning they measure less than 90 degrees each. The Pythagorean theorem can be applied to solve for the lengths of the sides of a right triangle.
Two equal lengths and two equal angles.
A triangle has no sum. There can be a sum of the measures of two or more angles, or the lengths of two or more sides, for example.
Proportional to the sine of the angles opposite them.
The base angles of an isosceles triangle that has two equal sides are equal.
That depends on the given information but an isosceles triangle has two equal side lengths and two equal interior angles.
You can't. To calculate another side length you need an angle. you need either two angles and a side length, or two side lengths and an angle to solve for other angles or side lengths. No matter what the case, you need three pieces of information i do not understnd it
They are in the same proportion as the sines of the angles that are opposite them.
it's a triangle (three sides) with two sides having equal lengths and angles
You will also need the angles so that you can use the Isosceles Triangle Theorems to solve for the base of isosceles triangle when only two sides are given.
