If the equation of an ellipse is in standard form and the denominators are equal, then the ellipse is a circle. True or False?

Respuesta :

I believe the correct answer is true. If the equation of an ellipse is in standard form and the denominators are equal, then the ellipse is a circle. The equation of the ellipse in this case will reduce to an equation of a circle. Hope this answers the question. Have a nice day.

Answer:

The statement is a TRUE statement.

Step-by-step explanation:

We know that the standard form of an ellipse is given as:

[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1[/tex]

where a and b are the x and y-intercepts respectively.

Also when the denominator i.e. a=b then,

[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{a^2}=1\\\\\\x^2+y^2=a^2[/tex]

Hence, we get the general equation of a circle whose center is at the origin and radius is 'a' or 'b' units.

Hence, the statement:

If the equation of an ellipse is in standard form and the denominators are equal, then the ellipse is a circle is a TRUE statement.
