Solid Geometry[ပလေဝ်ဒါန် တမ်ကၞက်]
Solid Geometry is the geometry of three-dimensional space, the kind of space we live in.
Three Dimensions[ပလေဝ်ဒါန် တမ်ကၞက်]
Shapes[ပလေဝ်ဒါန် တမ်ကၞက်]
Torus[ပလေဝ်ဒါန် တမ်ကၞက်]
Cylinder (ထၜောမ်)[ပလေဝ်ဒါန် တမ်ကၞက်]
Cone[ပလေဝ်ဒါန် တမ်ကၞက်]
Cube[ပလေဝ်ဒါန် တမ်ကၞက်]
cuboid[ပလေဝ်ဒါန် တမ်ကၞက်]
Triangular Pyramid[ပလေဝ်ဒါန် တမ်ကၞက်]
Square Pyramid[ပလေဝ်ဒါန် တမ်ကၞက်]
Prisms[ပလေဝ်ဒါန် တမ်ကၞက်]
Plane Geometry[ပလေဝ်ဒါန် တမ်ကၞက်]
Plane Geometry is all about shapes on a flat surface (like on an endless piece of paper).
Point; A Point has no dimensions, only position Line; A Line is one-dimensional Plane; A Plane is two dimensional (2D) Solid; A Solid is three-dimensional (3D)
Triangles[ပလေဝ်ဒါန် တမ်ကၞက်]
A triangle has three sides and three angles. The three angles always add to 180°.
Equilateral Triangle[ပလေဝ်ဒါန် တမ်ကၞက်]
Three equal sides. Three equal angles, always 60°
Isosceles Triangle Two equal sides Two equal angles
Scalene Triangle No equal sides No equal angles
Acute Triangle All angles are less than 90°
Right Triangle Has a right angle (90°)
Obtuse Triangle Has an angle more than 90°
Right-Angled Triangles A right-angled triangle (also called a right triangle) is a triangle with a right angle (90°) in it.
Two Types There are two types of right angled triangle:
Isosceles right angled triangle
One right angle Two other equal angles always of 45° Two equal sides
Scalene right-angled triangle
One right angle Two other unequal angles No equal sides
