Construct triangles for the following measurements where the angle is included. Class 7
Question 1.
Construct triangles for the following measurements where the angle is included between the sides: Class 7
(a) 3 cm, 75°, 7 cm
(b) 6 cm, 25°, 3 cm
(c) 3 cm, 120°, 8 cm
Solution:
Do as directed. Using the same procedure as given in the textbook.
Question 2.
We have seen that triangles do not exist for all sets of sidelengths. Is there a combination of measurements in the case of two sides and the included angle where a triangle is not possible? Justify your answer using what you observe during construction. Class 7
Solution:
No. In every case, we were able to obtain the third vertex.
