Exercise 7.1

Refer page 3-5 for exercise 7.1 in the PDF.

1. Complete the following statements:

a) Two line segments are congruent if.

Ans: Two objects or shapes are said to be congruent if they have the same shape and size and can coincide with each other.

Two line segments will be considered congruent if they have the same length.

b) Among two congruent angles, one has a measure of $70^\circ$, the measure of other angle is.

Ans: Two objects or shapes are said to be congruent if they have the same shape and size and can coincide with each other.

Therefore, two angles are said congruent if they have the same angle measure.

Thus, the measure of another angle is also $70^\circ$.

c) When we write $\angle A = \angle B$, we actually mean.

Ans: Two objects or shapes are said to be congruent if they have the same shape and size and can coincide with each other.

Therefore, two angles are said congruent if they have the same angle measure.

Thus, when it is written that $\angle A = \angle B$ it actually means that the measure of both the angles are equal. That means $m\angle A = m\angle B$.

2. Given any two real time examples for congruent shapes.

Ans: Two objects or shapes are said to be congruent if they have the same shape and size and can coincide with each other.

Two examples in real life for congruent shapes are:

1. Take the example of two footballs. They have the same shape and also the same size. Thus, the two footballs are congruent.

2. Take the example of two wheels of a bicycle. They have the same shape and also the same size. Thus, the two bicycle wheels are congruent.

3. If $\Delta ABC \cong \Delta FED$ under the correspondence $ABC \leftrightarrow FED$, write all the corresponding congruent parts of the triangles.

Ans: Two triangles will be considered congruent under a given correspondence if two sides and angle between those two sides of the given one triangle is equal to corresponding sides and angle of another triangle.

Draw two triangles $\Delta ABC \cong \Delta FED$.

It is given that $\Delta ABC \cong \Delta FED$ thus their corresponding sides are also congruent.

Therefore, it can be concluded that corresponding parts of the triangles are$\angle A \leftrightarrow \angle F$, $\angle B \leftrightarrow \angle E$, $\angle C \leftrightarrow \angle D$, $\overline {AB} \leftrightarrow \overline {EF}$, $\overline {BC} \leftrightarrow \overline {ED}$, $\overline {AC} \leftrightarrow \overline {FD}$.

4. If $\Delta DEF \cong \Delta BCA$ write the part(s) of $\Delta BCA$ that corresponds to:

a) write the part(s) of $\Delta BCA$ that corresponds to $\angle E$.

Ans:

Two triangles will be considered congruent if two sides and angle between those two sides of one triangle is equal to corresponding sides and angle of another triangle.

It is given that $\Delta DEF \cong \Delta BCA$. Thus, the angle corresponding to $\angle E$ is $\angle C$.

b) write the part(s) of $\Delta BCA$ that corresponds to $\overline {EF}$.

Ans:

Two triangles will be considered congruent if two sides and angle between those two sides of one triangle is equal to corresponding sides and angle of another triangle.

It is given that $\Delta DEF \cong \Delta BCA$. Thus, the side corresponding to $\overline {EF}$ is $\overline {CA}$.

c) write the part(s) of $\Delta BCA$ that corresponds to $\angle F$.

Ans:

Two triangles will be considered congruent if two sides and angle between those two sides of one triangle is equal to corresponding sides and angle of another triangle.

It is given that $\Delta DEF \cong \Delta BCA$. Thus, the angle corresponding to $\angle F$ is $\angle A$.

d) write the part(s) of $\Delta BCA$ that corresponds to $\overline {DF}$.

Ans:

Two triangles will be considered congruent if two sides and angle between those two sides of one triangle is equal to corresponding sides and angle of another triangle.

It is given that $\Delta DEF \cong \Delta BCA$. Thus, the side corresponding to $\overline {DF}$ is $\overline {BA}$.
