The four congruence theorem for right triangles are:
- LL Congruence Theorem --> If the two legs of a right triangle is congruent to the corresponding two legs of another right triangle, then the triangles are congruent.
- LA Congruence Theorem --> If a leg and an acute angle of a right triangles is congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.
- HA Congruence Theorem --> If the hypotenuse and an acute angle of a right triangle is congruent to the corresponding hypotenuse and acute angle of another triangle, then the triangles are congruent.
- HL Congruence Theorem --> If the hypotenuse and a leg of a right triangle is congruent to the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent.
The postulates that involve congruence are the following :SSS (Side-Side-Side) Congruence Postulate - If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.SAS (Side-Angle-Side) Congruence Postulate - If two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.ASA (Angle-Side-Angle) Congruence Postulate - If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.The two other congruence postulates are :AA (Angle-Angle) Similarity Postulate - If two angles of one triangle are congruent to two angles of another triangle, the triangles are similar.Corresponding Angles Postulate - If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.
A right triangle had 2 perp.sides. Perp. lines meet to form right angles. i need the answer in a four letter word. :)
four triangle faces.
A regular polygon is one in which all of the sides are congruent and all the angles are congruent. In the case of a triangle, congruence of sides implies congruence of angles and conversely. However, this is not true of any polygon with more than three sides.For example, the sides of a rhombus are all equal but the angles need not be. Similarly, all four angles of a rectangle are equal (90 deg) but the sides need not be.
No, not every triangle is half of a rectangle. A rectangle has four sides and four right angles, while a triangle has three sides and three angles. The area of a triangle is not necessarily half of the area of a rectangle with the same base and height. Triangles and rectangles are different geometric shapes with distinct properties.

No, a triangle and a square cannot be congruent because congruence requires that two shapes have the same size and shape. A triangle has three sides and three angles, while a square has four equal sides and four right angles. Therefore, their fundamental properties are different, making it impossible for them to be congruent.
isoceles Triangle, Scalene triangle, Equilateral Triangle and Right Triangle.
A rectangle has four sides whereas a right angle triangle has only three sides.
four types aressssasrhsasa1.HyL Theorem (Hypotenuse-Leg) - if the hypotenuse and leg of one triangle is congruent to another triangle's hypotenuse and leg, then the triangles are congruent.2.HyA (Hypotenuse-Angle) - if the hypotenuse and angle of one triangle is congruent to another triangle's hypotenuse and angle, then the triangles are congruent.3.LL (Leg-Leg) if the 2 legs of one triangle is congruent to another triangle's 2 legs, then the triangles are congruent.4.LA (Leg-Angle) if the angle and leg of one triangle is congruent to another triangle's angle and leg, then the triangles are congruent.
A triangle cannot have four angles.
No.
It is the right angle triangle which has 3 sides whereas all quadrilaterals have 4 sides.
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
In mathematics, properties of shapes refer to the characteristics and attributes that define and describe those shapes. These can include attributes such as the number of sides, angles, symmetry, area, perimeter, and congruence. Properties help in classifying shapes and understanding their relationships, providing a foundation for geometric concepts and theorems. For example, a rectangle has the properties of having four right angles and opposite sides that are equal in length.

No. Quadrilateral means "four sides." Triangles have three sides.
