Question

Observe the given figure and answer the following :
i) Identify and write the names of the triangles.
ii) Write the seven angles.
iii) Write six line segments.
iv) Which two triangles have $\angle B$ as common?

Answer 1

i) from the given figure we can observe that $\Delta ABC$, $\Delta ABD$ and $\Delta ADC$ are the triangles.

ii) from the given figure we can observe that $\angle BAC$, $\angle ABD$, $\angle BAD$, $\angle ADB$, $\angle DAC$, $\angle ACD$ and $\angle ADC$ are the angles.

iii) from the given figure we can observe that $AB,AC,AD,BD,BC,DC$ are the line segments.

iv) from the given figure we can observe that $\Delta ABC$, $\Delta ABD$ have $\angle B$ have common.
