In the figure what is m angle c - Math Workbook
WebThe medians of the triangle are represented by the line segments m a, m b, and m c. The length of each median can be calculated as follows: Where a, b, and c represent the length of the side of the triangle as shown in the figure above. As an example, given that a=2, b=3, and c=4, the median m a can be calculated as follows: Inradius WebFrom the figure, we understand that ∠ 1 and ∠ 3 together form a straight line. Thus, ∠ 1 + ∠ 3 = 1 8 0 0 ⇒ 3 5 0 + ∠ 3 = 1 8 0 0 ⇒ ∠ 3 = 1 4 5 0 Now, since l and m are parallel lines cut by transversals s and t, ∠ 3 an ∠ 4 are corresponding angles. We know that corresponding angles are equal. Thus ∠ 4 = ∠ 3 = 1 4 5 0 ... WebFeb 2, 2024 · An exterior angle of a triangle is equal to the sum of the opposite interior angles. Every triangle has six exterior angles (two at each vertex are equal in measure). The exterior angles, taken one at each vertex, always sum up to 360 ° 360\degree 360°. An exterior angle is supplementary to its adjacent triangle interior angle. lassi joghurt
