There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS and HL. 1. SSS (side, side, side) SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. For example: (See Solving SSS Triangles to discover more)

2023年2月5日 · 判斷全等的方法 有五種，分別是 SSS全等性質 、 SAS全等性質 、 ASA全等性質 、 AAS全等性質 、 RHS全等性質。 這裡要注意「S」指的是「邊」，「A」指的是 角， 非常重要！ 因為光看名字就能知道前四個全等性質是什麼了。 像是第一個 SSS 就是跟 三個邊 有關、 SAS 就是 兩個邊與一個角 、另外 ASA 與 AAS 都是 兩個角與一個邊 、差別在 角與邊的相對關係，下面會詳細介紹。 而 RHS 則是最特別，專門用在 直角三角形 上的。 剛剛說到 SSS 是跟三個 …

2023年1月11日 · Let's take a look at the three postulates abbreviated ASA, SAS, and SSS. The Angle Side Angle Postulate (ASA) says triangles are congruent if any two angles and their included side are equal in the triangles. An included side is the side between two angles. In the sketch below, we have CAT and BUG.

If any two sides and angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.

2019年7月14日 · AAS：由三角形内角和直接变成ASA情形。 SSS：设AB=DE，BC=EF，CA=FD。 把AB与DE变换至A、D重合，B、E重合，且C、F分别在它们的两侧。 连接CF，由边相等，CF的两侧是两个等腰三角形。 从而AB是CF的垂直平分线，进而是CAF、CBF的角平分线。 于是得到一对角相等，转化为SAS情形。 SAS, ASA, AAS, SSS, HL其他答主也解释了，那么我解释解释为什么AAA与SSA不能成立叭。 废话不多说直接上图。 AAA …

Both SAS and SSS rules are the triangle congruence rules. The full form of SAS is "Side-Angle-Side" and SSS stands for "Side-Side-Side." In the SAS postulate, two sides and the angle between them in a triangle are equal to the corresponding two sides and the angle between them in another triangle.

2024年9月16日 · ASA (Angle, Side, Angle) Congruency Rule. In the ASA congruence rule, two triangles are said to be congruent if any two angles and sides included between the two angles of one triangle are equal to the angles and sides of the corresponding triangle. Then the two triangles will satisfy the ASA congruency. In the above-given figure, we can see that,

SAS stands for “side, angle, side” and means that we have two triangles where we know two sides and the included angle are equal. If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent. ASA (angle, side, angle)

Triangles that have the same size and shape, meaning that they have identical side lengths and angle measures. (0:55) Side-Side-Side (SSS) Rule: If all three sides of two triangles are equal, the triangles are congruent. (1:28) Side-Angle-Side (SAS) Rule: Two triangles are congruent if they share two equal sides and the angle between them.
