Annual Revision I - A Tale of three intersecting lines
11.
TBQ - Match the procedure with the geometry
Question:
4
m.
Construct triangles for the following measurements:
\(75°, 5 \ cm, 75°\)
Match the geometry with the construction:
Answer variants:
Construction
Geometry
Step -1:
Place the protractor at B and construct ∠ B = 75° by drawing the other arm of the angle.
Draw a base line segment AB = 5 cm.
Mark the intersecting point of the two arms as the vertex C.
Place the protractor at A and construct ∠A = 75° by drawing the other arm of the angle.
Step -2:
First, place the protractor at A and construct ∠A = 75° by drawing the other arm of the angle.
Mark the intersecting point of the two arms as the vertex C.
Secondly, place the protractor at B and construct ∠ B = 75° by drawing the other arm of the angle.
Draw a base line segment AB = 5 cm.
Step -3:
Mark the intersecting point of the two arms as the vertex C.
Secondly, place the protractor at B and construct ∠ B = 75° by drawing the other arm of the angle.
Draw a base line segment AB = 5 cm.
First, place the protractor at A and construct ∠A = 75° by drawing the other arm of the angle.
Step -4:
Place the protractor at B and construct ∠ B = 75° by drawing the other arm of the angle.
Draw a base line segment AB = 5 cm.
Place the protractor at A and construct ∠A = 75° by drawing the other arm of the angle.
Mark the intersecting point of the two arms as the vertex C.
Thus, \(ABC\)
is the required triangle
