Classification of Angles:

Straight or Reflex Angle
Explanation:
Mamili ka na lang sa Straight and Reflex Angle. ung mga sagot na yan dun ilalagay sa oblong na walang laman. dun sa illustration, idodrawing mo. kunwari sa Acute Angle, idodrawing mo itsura nun.
Point- A point is the most fundamental object in geometry. It is represented by a dot and named by a capital letter. A point represents position only; it has zero size.
Line- In geometry, a line can be defined as a straight one- dimensional figure that has no thickness and extends endlessly in both directions. It is often described as the shortest distance between any two points.
Plane- In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space.
Line Segments- In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints.
Ray- In geometry, a ray can be defined as a part of a line that has a fixed starting point but no end point. It can extend infinitely in one direction. On its way to infinity, a ray may pass through more than one point. The vertex of the angles is the starting point of the rays.
Acute Angle- an angle that measures less than 90 degrees.
Right Angle- an internal angle which is equal to 90 degrees.
Obtuse Angle- has a measurement greater than 90 degrees but less than 180 degrees.
Straight Angle- an angle equal to 180 degrees.
Reflex Angle- measures more than 180 degrees but less than 360 degrees.
