Solving Geometry Problems
Finding lengths of sides or perimeters of triangles
- The perimeter of the triangle in the diagram is 21 inches. Find the
lengths of the sides.
- In ΔABC the length of AB is 3 more than the length of
BC, the length of AC is 2 less than twice the length of BC. If the perimeter
is 17 cm, find the length of each of its sides.
- Find the lengths of the sides of the triangle
in the diagram if the perimeter is 20.
- In an isosceles triangle, AB = AC and AB = 2BC. If the
perimeter of the triangle is 15, find the lengths of the sides.
- Find the lengths of the sides of the triangle in
the diagram if the perimeter is 16.
- In a triangle the lengths of sides AB, BC and AC are in
the ratio of 3 : 4 : 5. If the perimeter of the triangle is 36, find the
length of each of its sides.
- In ΔABC, the length of AB is 8, the length of BC is 2
less than the length of AC. The perimeter of the triangle is 6 less than three
times the length of AC. Find the length of each of its sides.
- Find the lengths of the sides of the triangle as shown
in the diagram if the perimeter is 24.
