Question 702088
Use a protractor and a straightedge to draw a triangle that has a right angle and a 30 degree angle. Then measure the shortest and longest sides of the triangle to the nearest millimeter. What is the relationship of the two measurements.

1.
first draw a line segment and mark one point with C where you will have  the vertex of 90° angle, you can use your protractor to draw this line, as the protractor includes a straight edge
 
2.

align the the guide markings on the protractor so that the line is at the 0-degree mark.


3.

make a mark by the 90°  point on the protractor using a pen or pencil

4.

move the protractor so that the straight edge connects the vertex point and the mark you made at 90 degrees, use a straight edge of the protractor and connect the two points

5.
ones you got 90° , use one leg of the angle set a point B (the vertex point  of   30°  angle)to any convenient width,  align the the guide markings on the protractor so that the line is at the 0-degree mark at B
6.
make a mark by the 30°  point on the protractor

7.
use a straight edge of the protractor, aline point B and mark of the 30°  point and draw a line  from B through  mark of the 30°  point  and continue until line intersect leg of the angle of 90°  and you will get your right angle triangle

since one angle is  90°   and another one is  30°  , means that third angle is  60°  

so, you will have  30°  - 60°  - 90°  right triangle which and the ratio of this triangle's longest side to its shortest side is "two to one" which means, the longest side is twice as long as the shortest side
