Construct a 90° angle from a line p g which is 7 centimetres. From the angle byset it to get 45 centimetres.

Here are the steps to construct a 90^ angle and then bisect it to get a 45^ angle: 1. Construct a 90^ angle from a line PQ which is 7 centimetres. Step 1: Draw a line segment. Draw a straight line segment PQ that is 7 cm long. Step 2: Mark a point. Choose a point R on the line segment PQ. For simplicity, you can choose R to be at one end (e.g., P) or anywhere along the line. Let's assume you want to construct the 90^ angle at point R. Step 3: Draw an arc. Place the compass needle at point R and draw an arc that intersects the line PQ at two points. Let's call these points A and B. Step 4: Draw intersecting arcs. With the compass needle at point A, open the compass to a radius greater than half the distance between A and B. Draw an arc above the line PQ. Without changing the compass radius, place the needle at point B and draw another arc that intersects the first arc. Let's call the intersection point C. Step 5: Draw the perpendicular line. Draw a straight line from point R through point C. This line will be perpendicular to PQ, forming a 90^ angle at R. 2. From the angle bisect it to get 45 degrees. Step 1: Identify the angle to bisect. You have constructed a 90^ angle, let's say CRQ. You need to bisect this angle. Step 2: Draw an arc. Place the compass needle at point R (the vertex of the 90^ angle). Draw an arc that intersects both arms of the 90^ angle (RC and RQ). Let's call the intersection points D on RC and E on RQ. Step 3: Draw intersecting arcs. With the compass needle at point D, open the compass to a radius greater than half the distance between D and E. Draw an arc inside the 90^ angle. Without changing the compass radius, place the needle at point E and draw another arc that intersects the first arc. Let's call the intersection point F. Step 4: Draw the angle bisector. Draw a straight line from point R through point F. This line RF bisects the 90^ angle, creating two 45^ angles ( CRF and FRQ). You have now constructed a 90^ angle and then bisected it to get a 45^ angle. Send me the next one 📸
