explain how you can use a straight edge and a compass to construct an angle that is both congruent and adjacent to a given angle.
To construct an angle that is both congruent and adjacent to a given angle using a straight edge and a compass, follow these steps:
1. Start by drawing a ray (half-line) as one side of the given angle. This will be the starting point for constructing the new angle.
2. Place the compass on the vertex (the common endpoint) of the given angle and draw an arc that intersects the ray you just drew. Label this intersection point as point A.
3. Without changing the compass width, place the compass on point A and draw another arc that intersects the ray you drew in step 1. Label this intersection point as point B.
4. Now, using a straight edge, draw a line connecting the vertex of the given angle to point B. This line will be the second side of the new angle.
5. Finally, mark the intersection of the new angle's side (line segment AB) and the original angle (the initial ray you drew). This point of intersection will serve as the vertex of the new angle.
Now you have successfully constructed an angle that is both congruent and adjacent to the given angle using only a straight edge and a compass.
