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.
right-angled triangle Triangle in which one of the angles is a right angle (90). It is the basic form of triangle for defining trigonometrical ratios (for example,sine, cosine, and tangent ) and for which Pythagoras theorem holds true. Its are a is equal to half the product of the len...

Unless you’re told otherwise, angles are usually rounded to one place of decimals. Example Find the size of angle a° Step 1The two sides we know areAdjacent (6,750) andHypotenuse (8,100). Step 2SOHCAHTOA tells us we must useCosine. ...
If two angles in a right triangle have equal measures, each measures( ). A: B: C: D: 相关知识点: 试题来源: 解析 B The measures of the acute angles are equal and . 如果一个直角三角形中的两个角的读数相等,那么每个角的度数都为( ). . . . . 锐角的度数相等,. 故选....
Now we know the measure of two angles are 39∘ and 69∘. By the Triangle Sum Theorem, the sum of all angles in a triangle is 180∘, so the final angle is 72∘ . Therefore, the largest angle in the triangle is (B) 72.反馈...
