WebThe proof shown in the video only works for the internal angles of triangles. With any other shape, you can get much higher values. Take a square for example. Squares have 4 angles of 90 degrees. That's 360 degrees - definitely more than 180. A regular pentagon (5-sided polygon) has 5 angles of 108 degrees each, for a grand total of 540 degrees. WebTherefore, the unknown angle can be calculated using the formula. Sum of interior angles of a triangle = Angle 1 + Angle 2 + Angle 3. ⇒ 180° = 45° + 63° + Angle 3. ⇒ Angle 3 = 180° - (45° + 63°) Angle 3 ⇒ 72°. ∴ The third angle is 72°. Example 3: The height of a triangle is 360 feet and the base is 270 feet.
Why can a triangle only have one right angle? – WisdomAnswer
WebDec 12, 2015 · No, an obtuse triangle can not have more than one obtuse angle. This is because all of the angles have to add up to 180 and the smallest obtuse angle you can have is 91 degrees. So 180-91=89. 89 degrees is the angle that you need to complete the triangle and it is an acute angle. WebTherefore, a triangle can never have more than one obtuse angle. When an angle of a triangle is 90 degrees, the triangle cannot have an obtuse angle. The other two must each be less than 90 ... flu public service announcement
Why can a right triangle have only on right angle? - Answers
WebFeb 2, 2024 · If you had two or more obtuse angles, their sum would exceed 180° and so they couldn't form a triangle. For the same reason, a triangle can't have more than … WebA triangle cannot have more than right angles. Login. Study Materials. NCERT Solutions. ... One ; Because the sum of all the angles should be 180 ... (iii) A triangle can have all angles more than 60 ... WebIn a right triangle, the two variable angles are always less than 90° (See Interior angles of a triangle). But we can in fact find the tangent of any angle, no matter how large, and also the tangent of negative angles. For more on this see Functions of large and negative angles. When used this way we can also graph the tangent function. flup up helmet for women
