直角銳角鈍角區分？

在平面幾何中，它們是三個(gè)不同度數的角。直角是指90度的角，大于0度小于90度的角是銳角，大于90度小于180度的角是鈍角。

直角銳角鈍角區分？

一、角度大小不同:

小于90°的角是銳角;

等于90°的角是直角;

大于90°小于180°的角是鈍角。

二、三角形中的個(gè)數不同:

一個(gè)三角形只能有一個(gè)鈍角或直角，可以有二到三個(gè)銳角。

銳角(acute angle):大于0°，小于90°的角叫做銳角。

直角(right angle):等于90°的角叫做直角。

鈍角(obtuse angle):大于90°而小于180°的角叫做鈍角。

平角(straight angle):等于180°的角叫做平角。

優(yōu)角(major angle):大于180°小于360°叫優(yōu)角。

劣角(minor angle):大于0°小于180°叫做劣角，銳角、直角、鈍角都是劣角。

周角(round angle):等于360°的角叫做周角。

負角(negative angle):按照順時(shí)針?lè )较蛐D而成的角叫做負角。

正角(positive angle):逆時(shí)針旋轉的角為正角。

零角(zero angle):等于0°的角。

等于90°的角叫直角；大于90°小于180°的角叫鈍角；大于0°小于90°的角叫銳角，它們三個(gè)度數不同。具有公共端點(diǎn)的兩條射線(xiàn)組成的圖形叫做角。這個(gè)公共端點(diǎn)叫做角的頂點(diǎn)，這兩條射線(xiàn)叫做角的兩條邊。

角的種類(lèi)

角的大小與邊的長(cháng)短沒(méi)有關(guān)系；角的大小決定于角的兩條邊張開(kāi)的程度，張開(kāi)的越大，角就越大，相反，張開(kāi)的越小，角則越小。在動(dòng)態(tài)定義中，取決于旋轉的方向與角度。角可以分為銳角、直角、鈍角、平角、周角。

角的規律

1、過(guò)兩點(diǎn)只有一條直線(xiàn)

2、兩點(diǎn)之間線(xiàn)段最短

3、同角或等角的補角相等

4、同角或等角的余角相等

5、過(guò)一點(diǎn)有且只有一條直線(xiàn)和已知直線(xiàn)垂直

6、直線(xiàn)外一點(diǎn)與直線(xiàn)上各點(diǎn)連接的所有線(xiàn)段中，垂線(xiàn)段最短。
