Question

What other name can you give to the line of symmetry of i. an isosceles triangle? ii. a circle?

Answer 1

1)

From the diagram above it can be seen that the measuring line of the isosceles triangle is.

• Therefore, in the isosceles triangle another name for the line measuring meters and height of the triangle.

2)

From the diagram above it can be seen that the line of measurement of the circle is infinite.

• Therefore, in a circle another name for the corresponding line is the width of the circle.

Answer 2

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R༄✯☆❀✿}}}}$

a) An isosceles triangle has only one line of symmetry which can also be called the median/altitude of the isosceles triangle.

b) There are infinite lines of symmetry in a circle which can also be called as the diameter of the circle.
