Right angle is equal to
WebFeb 10, 2024 · c² = a² + b² - 2ab × cos (γ) For a right triangle, the angle gamma, which is the angle between legs a and b, is equal to 90°. The cosine of 90° = 0, so in that special case, the law of cosines formula is reduced to the well-known equation of Pythagorean theorem: a² = b² + c² - 2bc × cos (90°) a² = b² + c².

WebAn angle which is measuring less than 90 degrees is called an acute angle. This angle is smaller than the right angle (which is equal to 90 degrees). For example, ∠30 o, ∠45 o, ∠60 o, ∠75 o, ∠33 o, ∠55 o, ∠85 o, etc. are all acute angles. Let us see some examples here to understand. Example: See the figure below: WebProp. 31 (problem): To draw a straight line through the given point parallel to the given line.
