## How do you find two angles of a triangle with one angle?

Use the sine rule if given only one angle and two lengths of a triangle. The formula is sin A/a = sin B/b, where “A” and “B” are angles and “a” and “b” are the lengths of the sides opposite these angles, respectively.

**What is a triangle with 2 angles?**

An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length. . This property is equivalent to two angles of the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles.

### What do you call to non right triangle?

Any triangle that is not a right triangle is an oblique triangle. Solving an oblique triangle means finding the measurements of all three angles and all three sides.

**How to find angle with 2 sides?**

These are the four steps we need to follow: Find which two sides we know – out of Opposite, Adjacent and Hypotenuse. Use SOHCAHTOA to decide which one of Sine, Cosine or Tangent to use in this question. For Sine calculate Opposite/Hypotenuse, for Cosine calculate Adjacent/Hypotenuse or for Tangent calculate Opposite/Adjacent.

## What is the formula for determining sides of a triangle?

How to find the sides of a right triangle if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √ (c² – if leg b is unknown, then b = √ (c² – a²) for hypotenuse c missing, the formula is c = √ (a² + b²)

**What triangle has only 2 sides?**

An isosceles triangle has two sides of equal length, and one side that is either longer or shorter than the equal sides. Angle has no bearing on this triangle type. Equilateral

### What is triangle with 2 even sides called?

Isosceles . An isosceles triangle can be drawn in many different ways. It can be drawn to have two equal sides and two equal angles or with two acute angles and one obtuse angle. It is easy to work…
