Angle from Any Two Sides We can find anunknown anglein aright-angled triangle, as long as we know the lengths oftwo of its sides. Example The ladder leans against a wall as shown. What is theanglebetween the ladder and the wall?
An interior angle of a triangle is formed by two sides of the triangle. An exterior angle is formed by one side of the triangle and the extension of an adjacent side. Each exterior angle has two remote interior angles. A remote interior angle is an interior angle that is not adjacent to...

How to Find the Angle of a Right Triangle If you know the lengths of two sides of a right triangle, then you can determine the interior angles using the trigonometric functions sine, cosine, and tangent. These are usually shortened to sin, cos, and tan. To find the angle given two si...
在一个三角形中，已知一个角和两条边，解释其不确定性。解：（1）当该角为已知边所夹时，三角形唯一；（2） 当不是已知边所夹时 (i) 若已知角大于等于90度，三角形唯一，(ii) 若已知角为锐角时三角形不唯一（有两种情况）。两
How to find the angle of a right triangle If you know one angle apart from the right angle, the calculation of the third one is a piece of cake: Given β: α = 90 - β Given α: β = 90 - α However, if only two sides of a triangle are given, finding the angles of a righ...
Problem 6: The measures of the sides of a right tri-angle are 60, 80 and 100. Find the measure of a line segment, drawn from the vertex of the right angle to the hypotenuse, that divides the triangle into two triangles of equal perimeters. (Fig. 48)A BD CFig. 48 ...
The meaning of RIGHT ANGLE is the angle bounded by two lines perpendicular to each other : an angle of 90° or 1/2 π radians. How to use right angle in a sentence.
1. A right triangle has only one angle equal to 90∘.2. The angles other than the right angle must be less than 90∘.3. The side opposite to the vertex of 90∘ is called the hypotenuse.4. The other two sides adjacent to the right angle are called base and perpendicular....
