Analytical Geometry

100

I’m a shape with four equal sides, Opposite angles, matching in strides. A square by name, I’m known to be, What am I in geometry?

I am a Square

200

I’m formed by two rays with a common start, An angle in geometry, play your part. Measuring in degrees is my way, What geometric concept am I, do you say?

300

My center is a point of special grace, Equidistant from all points on my surface. In circles, I find my dwelling place, What geometric figure am I in this space?

I am a Circle

400

I start at the origin, no doubt, But travel in one direction, never deviate or turn about. My slope is constant, my path is clear, I’m a line that mathematicians hold dear.

I am a Straight Line.

I am a Rectangle.

Trigonometry

100

In a right-angled triangle, I'm always 90 degrees, I'm opposite to the hypotenuse, don't you agree? What am I?

Right angle

200

I'm the ratio of the opposite side to the adjacent, In a right-angled triangle, my value is adjacent. What am I?

Tangent

300

I'm the angle between the adjacent and the hypotenuse, In a right-angled triangle, I'm what you'll deduce. What am I?

Cos

400

I'm the ratio of the opposite side to the hypotenuse, In a right-angled triangle, I'm what you'll use. What am I?

Sin

500

A right triangle with an angle that's not obtuse, Equal to half of 90, and a little obtuse. Which angle am I?

45 degrees

Statistics

100

 I am a measure of central tendency. I represent the middle value in a dataset when it is arranged in numerical order. What am I?

Median

200

 I am a measure of variability. I tell you how spread out the values in a dataset are. What am I?

Standard Deviation

300

 I am a graphical representation of the distribution of a dataset. I look like a series of boxes. What am I?

Box-and-Whisker Plot

400

I am the average of all the squared differences from the mean. What statistical measure am I?

Variance

500

 I am a measure of how much the values in a dataset vary from the mean. What am I?

Variability

letter "M"

200

 What has keys but can't open locks?

A piano.

300

I am the beginning of the end, and the end of time and space. I am essential to creation, and I surround every place. What am I?
