WebApr 13, 2024 · How to Measure an Obtuse Angle. To measure an obtuse angle, you can use a protractor. Align the base of the protractor with one side of the angle and then read the measurement from the degree scale. Alternatively, if you know the values of the other angles in a triangle or other shape, you can use those values to calculate the missing angle. WebFinding area of triangles Google Classroom About Transcript To find a triangle's area, use the formula area = 1/2 * base * height. Choose a side to use for the base, and find the height of the triangle from that base. Then, plug in the measurements you have for the base and height into the formula.

WebAn obtuse triangle has only one angle greater than 90° since the sum of the angles in any triangle is 180°. If one of the angles is greater than 90°, then the sum of the other two angles must be less than 90°, so the other two angles must both be acute angles. For DEF above, ∠D + ∠F = 60° < 90°, so ∠D and ∠F are acute angles. WebCircumcenter of Triangle.
