WebThe angle ACB is opposite the chosen vertex A, and is obtuse (greater than 90°). and is the reason the first step of the construction is to extend the base line, just in case this happens. The altitude meets the extended base BC of the triangle at right angles.. Printable step-by-step instructions. The above animation is available as a printable step-by-step instruction … Web$\begingroup$ Let $\theta = $ (bottom right angle of triangle). $9x + 12$ is the measure of the angle "supplementary" to $\theta$ (angle on outside the triangle formed by the right side and the line extended to the right from the bottom side of the triangle. Since two adjacent (next to each other) angles form a line (180 degrees), we get that $\theta + (9x + 12) = 180. WebThe angles inside a shape are called interior angles. If the side of a triangle is extended, the angle formed outside the triangle is the exterior angle . \(g\) is the interior angle the spider marvel 1602
