When designing a truss, a truss builder might know the base angle measurement and the lengur UI te te verleeu. 11
compute the height of the king post. Let's take a look at some right triangles to see whether knowing the measure of an acute angle of a right
triangle and the length of one of the sides is enough to find the lengths of the other two sides.
You will use GeoGebra to explore the trigonometric ratios when an acute angle is fixed for a given right triangle. Go to trigonometric ratios
and complete each step below. The right triangle represents half of a king post truss. If you need help, follow these instructions for using

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
