Find the value of the unknown angles in the given figures?
Unknown Angles in Figures
Figure 1
- Angle ABD = 60° (given)
- Angle CBD = 180° - 60° - 50° = 70° (sum of angles in a triangle)
- Angle ABC = 180° - 70° - 50° = 60° (sum of angles in a triangle)
Figure 2
- Angle ABD = 70° (given)
- Angle CBD = 110° (sum of angles in a triangle)
- Angle BCD = 180° - 110° - 30° = 40° (sum of angles in a triangle)
Figure 3
- Angle ABD = 70° (given)
- Angle BCD = 110° (sum of angles in a triangle)
- Angle DCE = 180° - 110° = 70° (opposite angles of a parallelogram)
- Angle CDE = 180° - 70° = 110° (opposite angles of a parallelogram)
- Angle AED = 180° - 70° - 110° = 0° (sum of angles in a triangle)
Figure 4
- Angle ABD = 80° (given)
- Angle BCD = 100° (given)
- Angle CDE = 180° - 100° = 80° (opposite angles of a parallelogram)
- Angle DCE = 180° - 80° = 100° (opposite angles of a parallelogram)
- Angle AED = 180° - 80° - 100° = 0° (sum of angles in a triangle)
Figure 5
- Angle ABD = 70° (given)
- Angle CBD = 110° (sum of angles in a triangle)
- Angle BCD = 180° - 110° - 30° = 40° (sum of angles in a triangle)
- Angle DCE = 180° - 70° = 110° (opposite angles of a parallelogram)
- Angle CDE = 180° - 110° = 70° (opposite angles of a parallelogram)
- Angle AED = 180° - 70° - 40° = 70° (sum of angles in a triangle)
